Large-amplitude oscillation dynamics and domain suppression in a superlattice Bloch oscillator
Herbert Kroemer
We analyze the current dynamics of a superlattice Bloch oscillator under conditions where, in addition to the dc bias field causing a negative differential ac conductivity, a simil…

On the nature of the negative-conductivity resonance in a superlattice Bloch oscillator
Herbert Kroemer
Adding a high-frequency ac component to the bias field of a superlattice induces a synchronous modulation of the velocity with which the electrons traverse the Brillouin zone. In t…
