The technology of single YSZ and double (YSZ on porous material) buffer layers preparation on Si and GaAs substrates is developed. By using porous substrate, we improved structure and morphology of YSZ buffer layers. It is shown, that III-V films received on YSZ substrates and buffer layers have single crystalline structure, good morphology and high electrophysical and photoluminescent properties. The use of the two-layer buffer in comparison with the single YSZ buffer improves adhesion of III-V films and raises its structural and electric homogeneity.

  • Influence of GaN surface morphology on characteristics of Al<inf>0,3</inf>Ga<inf>0,7</inf>N/GaN heterostructures created by molecular beam epitaxy

    The technique of forming III-N layers with low defects level is developed. It is based on method of molecular beam epitaxy with atomic force microscopy using. It is demonstrated that the structure perfection of layers, which is estimated by the surface defects number, is directly connected with two- dimensional electron gas (2DEG) characteristics in formed heterostructures.

  • Velocity overshoot effects and transit times in III-V nitride HFETs : a Monte Carlo study

    Monte Carlo simulation of AlGaN/GaN HEMTs were carried out and compared with GaAs based devices. The following outcomes of our simulations are noteworthy: i) partially due to the relatively heavy electron effective mass in GaN, the velocities of the electrons are mostly below the steady state values through most of the channel; ii) unlike what is observed in GaAs based short channel devices, there is no pronounced overshoot effect, even at high drain source biases, due to increased scattering; iii) our simulations show that the suppression of overshoot is directly related to the length of the high field region. This length is quite small for usual bias conditions. We suggest that a non-uniform composition of the barrier region could conceivably help in spreading out the high field region, which is present at the drain end of the device. Other results of the Monte Carlo simulation include transconductance, noise information and unity current gain frequency.

  • Resonant terahertz detection of 2DEG with grating coupler

    Plasmon-polariton detection by 2DEG has been modelled in several kinds of hetero-structures (AlGaN/GaN, InAlN/GaN, SiGe/Si/SiGe, AlGaAs/GaAs) with grating coupler. The resonances were discussed according to the heterojonction nature, the grating aspect ratio, the thickness of the layer above the quantum well and the sheet carrier concentration in the quantum well (QW) at various temperatures. The objective is to make possible the tuning of the resonances versus frequency in order to facilitate the control of the terahertz detection.
