Highly doped p-type 3C–SiC on 6H–SiC substrates

2019-11-11

Highly doped p-3C–SiC layers of good crystal perfection have been grown by sublimation epitaxy in vacuum. Analysis of the photoluminescence spectra and temperature dependence of the carrier concentration shows that at least two types of acceptor centers at ~EV + 0.25 eV and at EV + 0.06–0.07 eV exist in the samples studied. A conclusion is reached that layers of this kind can be used as p-emitters in 3C–SiC devices.

Photo-induced currents in CdZnTe crystals as a function of illumination wavelength

2019-11-05

We report variations in the currents of CdZnTe semiconductor crystals during exposure to a series of light emitting diodes of various wavelengths ranging from 470 to 950 nm. The changes in the steady-state current of one CdZnTe crystal with and without illumination along with the time dependence of the illumination effects are discussed. Analysis of the de-trapping and transient bulk currents during and after optical excitation yield insight into the behaviour of charge traps within the crystal. Similar behaviour is observed for illumination of a second CdZnTe crystal suggesting that the overall illumination effects are not crystal dependent.

Room-temperature bonding of GaAs//Si and GaN//GaAs wafers with low electrical resistance

2019-10-30

The electrical properties of room-temperature bonded wafers made from materials with different lattice constants, such as p-GaAs and n-Si, p-GaAs and n-Si [both with an indium tin oxide (ITO) surface layer], and n-GaN and p-GaAs, were investigated. The bonded p-GaAs//n-Si sample exhibited an electrical interface resistance of 2.8 × 10−1 Ωcm2 and showed ohmic-like characteristics. In contrast, the bonded p-GaAs/ITO//ITO/n-Si sample showed Schottky-like characteristics. The bonded n-GaN//p-GaAs wafer sample exhibited ohmic-like characteristics with an interface resistance of 2.7 Ωcm2. To our knowledge, this is the first reported instance of a bonded GaN//GaAs wafer with a low electrical resistance.

Epitaxial growth of Bi2Se3 layers on InP substrates by hot wall epitaxy

2019-10-21

The a-axis lattice parameter of Bi2Se3 is almost identical to the lattice periodicity of the InP (1 1 1) surface. We consequently obtain remarkably smooth Bi2Se3 (0 0 0 1) layers in hot-wall-epitaxy growth on InP (1 1 1)B substrates. The lattice-matched periodicity is preserved in the [1 1 0] and [] directions of the (0 0 1) surface. The Bi2Se3 layers grown on InP (0 0 1) substrates exhibit 12-fold in-plane symmetry as the [] direction of Bi2Se3 is aligned to either of the two directions. When the (1 1 1)-oriented InP substrates are inclined, the Bi2Se3 (0 0 0 1) layers are found to develop steps having a height of ~50 nm. The tilting of the Bi2Se3 [0 0 0 1] axis with respect to the growth surface is responsible for the creation of the steps. Epitaxial growth is thus evidenced to take place rather than van der Waals growth. We point out its implications on the surface states of topological insulators.

Mid-infrared InAs/GaSb strained layer superlattice detectors with nBn design grown on a GaAs substrate

2019-09-29

We report on a type-II InAs/GaSb strained layer superlattice (SLS) photodetector (λ_{\rm cut\hbox{-}off}  ~4.3 µm at 77 K) with nBn design grown on a GaAs substrate using interfacial misfit dislocation arrays to minimize threading dislocations in the active region. At 77 K and 0.1 V of the applied bias, the dark current density was equal to 6 × 10−4 A cm−2 and the maximum specific detectivity D* was estimated to 1.2 × 1011 Jones (at 0 V). At 293 K, the zero-bias D* was found to be ~109 Jones which is comparable to the nBn InAs/GaSb SLS detector grown on the GaSb substrate.

Overview of recent direct wafer bonding advances and applications

2019-09-18

Direct wafer bonding processes are being increasingly used to achieve innovative stacking structures. Many of them have already been implemented in industrial applications. This article looks at direct bonding mechanisms, processes developed recently and trends. Homogeneous and heterogeneous bonded structures have been successfully achieved with various materials. Active, insulating or conductive materials have been widely investigated. This article gives an overview of Si and SiO2 direct wafer bonding processes and mechanisms, silicon-on-insulator type bonding, diverse material stacking and the transfer of devices. Direct bonding clearly enables the emergence and development of new applications, such as for microelectronics, microtechnologies, sensors, MEMs, optical devices, biotechnologies and 3D integration.

Japanese Journal of Applied Physics logo A Novel Diffusion Resistant P-Base Region Implantation for Accumulation Mode 4H–SiC Epi-Channel Field Effect Transistor

2019-09-11

A novel implantation technique using the carbon (C) and boron (B) sequential implantation is employed to control the B lateral and vertical diffusion from the p-base region of the planar silicon carbide (SiC) epi-channel field effect transistor (ECFET). The current deep level transient spectroscopy measurements were performed to establish the inter-correlation between the B enhanced diffusion and the electrically active defects introduced by the C and B sequential implantation. It was found that the formation of deep defect level is completely suppressed for the same ratio (C:B=10:1) as that for the B diffusion in 4H–SiC. A diffusion mechanism which is correlated to the formation of D center was proposed to account for the experimentally observed B enhanced diffusion. The effectiveness of C and B implantation technique in suppressing the junction field effect transistor (JFET) pinch effect is clearly visible from the 3–4 fold increase in drain current of fabricated 4H–SiC ECFET for p-b...

Adding a Bit of Artificiality Makes Graphene Real for Electronics

2019-08-28

 We believes that one of the electronic capabilities for this device could be selecting the strength of the spin-orbit coupling in a p-type GaAs quantum well. This could lead to the creation of a topological insulator, which is an insulator on the inside but a conductor on the outside. Such an insulator could in turn enable so-called topological quantum computation, which is a theoretical approach to quantum computing that could be far more robust than current methods. This capability does not exist in natural graphene or other artificial graphene systems.

Two inch GaN substrates fabricated by the near equilibrium ammonothermal (NEAT) method

2019-08-19

This paper reports two inch gallium nitride (GaN) substrates fabricated from bulk GaN crystals grown in the near equilibrium ammonothermal method. 2'' GaN wafers sliced from bulk GaN crystals have a full width half maximum of the 002 X-ray rocking curve of 50 arcsec or less, a dislocation density of mid-105 cm−2 or less, and an electron density of about 2 × 1019 cm−3. The high electron density is attributed to an oxygen impurity in the crystal. Through extensive surface preparation, the Ga surface of the wafer shows an atomic step structure. Additionally, removal of subsurface damage was confirmed with grazing angle X-ray rocking curve measurements from the 114 diffraction. High-power p–n diode structures were grown with metalorganic chemical vapor deposition. The fabricated devices showed a breakdown voltage of over 1200 V with sufficiently low series resistance.

Enhancement of the quality of InAsSb epilayers using InAsSb graded and InSb buffer layers grown by hot wall epitaxy

2019-08-12

We have investigated the structural and electrical properties of InAsxSb1−x epilayers grown on GaAs(0 0 1) substrates by hot wall epitaxy. The epilayers were grown on an InAsSb graded layer and an InSb buffer layer. The arsenic composition (x) of the InAsxSb1−x epilayer was calculated using x-ray diffraction and found to be 0.5. The graded layers were grown with As temperature gradients of 2 and 0.5 °C min−1. The three-dimensional (3D) island growth due to the large lattice mismatch between InAsSb and GaAs was observed by scanning electron microscopy. As the thicknesses of the InAsSb graded layer and the InSb buffer layer are increased, a transition from 3D island growth to two-dimensional plateau-like growth is observed. The x-ray rocking curve measurements indicate that full-width at half-maximum values of the epilayers were decreased by using the graded and buffer layers. A dramatic enhancement of the electron mobility of the grown layers was observed by Hall effect measurements. So...
