We carefully scrutinize the potential of ultrathin body strained (111) GaAs MOSFETs to achieve better performance than other GaAs-based channel FETs at scaled channel length and with relaxed thickness requirements, thanks to L-valleys enhanced density-of-states (DoS) and carrier transport. Calibrated multi-subband Monte Carlo simulations including scattering provide the modeling framework necessary...
A comprehensive description of band gap and effective masses of III–V semiconductor bulk and ultra-thin body (UTB) structures under realistic biaxial and uniaxial strain is given using numerical simulations from four different electronic structure codes. The consistency between the different tools is discussed in depth. The nearest neighbor sp3d5s* empirical tight-binding model is found to reproduce...
