We propose and analyze a high-current III–V transistor design using electron transport in the Γ- and L-valleys of (111) GaAs. Using sp[su3}d5s* empirical tight-binding model for band-structure calculations and the top-of-the-barrier transport model, improved drive current is demonstrated using L-valley transport in a strained GaAs channel grown on an (111) InP substrate. At a body thickness of 2 nm...
The thermoelectric power-factor (PF) and efficiency (ZT) of GaAs nanowires (NWs) can be improved by (i) choosing a proper wire growth and channel orientation, (ii) by applying uniaxial tensile stress, and (iii) suitable wire cross-section size. In this work we study the impact of these three factors on the PF and the ZT. Tensile stress, channel direction and cross-section size allows bandstructure...
III–V semiconductors can provide a viable option for continuous scaling of future CMOS technology [1–3]. We report a significant enhancement in the ON-current (ION) of ultra-thin body (UTB) GaAs intrinsic channel p-MOSFETs using biaxial compressive strain. Our theoretical investigation shows that valence bands (VB) become hyperbolic under compressive strain in GaAs rendering effective mass approximation...
Ultra-scaled SiGe nanowire FETs (NWFETs) are an attractive candidate in achieving faster p-type devices compared to Silicon. This work investigates the performance of SiGe nanowire FETs (NWFETs) using a Virtual Crystal Approximation (VCA) method based on an atomistic Tight-Binding (TB) model. The electronic structure calculation is self- consistently coupled to a 2D Poisson solver. The spatial charge...
