摘要

We present an atomistic model explaining spontaneous reductions of source-drain current in suspended carbon nanotube field effect transistors (CNT FETs) under proton irradiation. The non-equilibrium Green's function (NEGF) method is used to investigate the local density of states (LDOS) and transfer characteristics of the device. Our model suggests that ionized gas species within 20 nm of the CNT ...
