Emergence of current branches in a series array of negative differential resistance circuit elements

Xu, Huidong; Teitsworth, Stephen (AMER INST PHYSICS, 2010)

We study a series array of nonlinear electrical circuit elements that possess negative differential resistance and find that heterogeneity in the element properties leads to the presence of multiple branches in current-voltage ...
On the possibility of a shunt-stabilized superlattice terahertz emitter

Xu, Huidong; Teitsworth, Stephen (AMER INST PHYSICS, 2010)

High field electronic transport through a strongly coupled superlattice (SL) with a shunting side layer is numerically studied using a drift-diffusion model that includes both vertical and lateral dynamics. The bias voltage ...
