Es. Daniel et al., Coupled drift-diffusion/quantum transmitting boundary method simulations of thin oxide devices with specific application to a silicon based tunnel switch diode, IEEE DEVICE, 47(5), 2000, pp. 1052-1060
We present a method of coupling drift-diffusion simulations with quantum tr
ansmitting boundary method (QTBM) tunnel current calculations. This allows
self-consistent simulation of thin oxide devices in which large tunnel curr
ents can flow. Simulated results are presented for a thin oxide Al/SiO2/Si
structure and an Al/SiO2/n-Si/p-Si tunnel switching diode. We demonstrate t
he careful use of the recombination lifetime as an adjustable or relaxable
parameter in order to obtain converging solutions.
