Abstract:
By using accurate Multi-Subband-Monte-Carlo simulations of
quasi-ballistic transport we carry out a detailed re-examination
of the experimental extraction procedure for the ballistic-ratio
BR=ID/IBAL in nanoMOSFETs proposed in [1]. It is found
that the ballistic-ratio extracted applying this procedure to the
simulated drain current severely underestimates the BR extracted
by directly compare the simulated ID and IBAL. This
is mainly due to inaccurate determination of the temperature
dependence of the inversion charge. It is suggested that this
limitation of the extraction procedure may explain the apparent
lack of improvement in the ballisticity with the geometrical
scaling.
