The Empirical Tight Binding(ETB) method is widely used in atomistic device simulations. The reliability of such simulations depends very strongly on the choice of basis sets and the ETB parameters.
The Piezoelectronic Transistor (PET) has been proposed as a post-CMOS device for fast, low-power switching. In this device the piezoresistive channel is metalized via the expansion of a relaxor piezoelectric element. The mixed-valence compound SmSe is a good choice of PET channel material …
