摘要
Quantum mechanical effect devices incorporate means for interrupting the two-dimensional carrier gas of a modulation doped structure to produce periodic potential variations which provide superlattice-like effects on current flowing nearby. The modulation doped structures incorporate specialized structures displaced from a current path which simultaneously confine the two-dimensional carrier gas into a quasi-one- dimensional carrier gas and subject the thus confined carrier gas and current flowing therein to superlattice-like effects by inducing periodic potential variations along the current path. The induced variations are produced by etching corrugations in the device edges or by forming them in biasing gates.
