Abstract :
We have applied nonequilibrium Green´s function (NEGF) formalism to triple barrier resonant tunneling diodes (TBRTD) structures for the first time in order to reproduce more realistic J-V curves measured experimentally than those derived by the conventional method. It is shown that the peak current density derived by NEGF can be the same order of magnitude measured experimentally and we can perform an improved estimation for the coherence of hot electrons by using NEGF formalism compared to results from the conventional method.
