Firstly, we use the existing Band gap Narrowing (BGN) models as a reference and determine the self-energy correction terms to be included in the Tight-Binding Hamiltonian of a thick and intrinsic SOI channel (43 nm, where quantum confinement effects are negligible) at room temperature, to ensure that the effects of n and p type doping can be accurately taken into account. By using the same self-energy correction terms, while also now including a temperature dependent band gap correction, we then quantify the extent of band gap narrowing for a wide range of device temperatures (15 K - 300 K), channel thicknesses and doping densities. We further evaluate the channel electrostatics of these devices through the self-consistent solution of the band structure with the Poisson’s equation.
