In this paper, we report the possibility of achieving sub-kT/q subthreshold slope (i.e. lower than 59.6 mV/decade at T=300K) without using either impact ionization or band-to-band tunneling. The device uses intraband tunneling within the conduction band through barriers whose shape varies with the applied gate voltage. Subthreshold slope as low as 56.5 mV/decade is reported at T=300K. The VBT reported here breaks the 60mV/dec barrier over more than five decades of subthreshold current, which is the highest current range reported so far.
