Abstract

Strong nonlinear response is an essential feature of narrow band transport. These potentially strong nonlinearities derive from the fact that a perturbation applied to a narrow band will exhaust the spectrum of states and the response will be saturated. The most exciting example is the long sought for but never achieved Bloch oscillation [1]. Here, we describe two different experiments that explore the saturated response of a narrow conduction band. First we discuss the effect of magnetic fields that drive the cyclotron resonance above the top of the mini-band and then, secondly, we document quenching of the narrow band conductivity at temperatures that exceed the mini-band width.
