Abstract

IWCE 2015 presentation. in this work we investigate the dependence of electron-phonon scattering in single dopant-based nanowire transistor with respect to temperature and dimensions. we use a 3d real-space non-equilibrium green': ; s function (negf) approach where electron-phonon scattering is treated within the selfconsistent born approximation (scba) through self-energies. we also use an analytic model to extend the validity of the acoustic phonon self-energy at low temperatures. based on this model our simulations show the presence of a current hysteresis when reducing the temperature down to 150 k. the influence of channel length and nanowire cross-section on the dopant level contribution to the current is also discussed.
