Abstract
Improved p-channel FETs and optoelectronic device make use of reduced hole effective mass achieved with quantum confinement. The devices include multiple one-dimensional p-channel FETs which have electrically induced and controllable one dimensional p-type semiconductor wires; square well two-dimensional p-channel FETs; and laser diodes and light emitting diodes which use one dimensional p-type semiconductor wires.
