Control of Electric Field Domain Formation in Multiquantum Well Structures

Abstract

The formation of electric field domains (EFD) was first observed in bulk GaAs and is mostly known as the cause of Gunn oscillations. It is explained in terms of the negative differential resistance (NDR) which occurs because of the electron transfer from the r to the X or L valleys. Esaki and Chang2 first observed the formation of static EFDs in multiquantum wells (MQW); this phenomenon was attributed to the NDR which arises due to sequential resonant tunneling (SRT) between subbands in adjacent wells.3-6
