Effect of the oxide thickness on the operation speed of a field-effect transistor in terms of the carrier tunneling rate

On the voltage sensitivity of current in electronic transport

“…The above conception is applicable to a number of situations in electron optics (see, for example, Refs. [1,2]) which can be explored in an elegant way. A notorious example of this is the evaluation of sensitivity of electron current-to-voltage and the discussion of aspects related to the associated differential conductance and electronic density of states.…”
