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.
Claims3
A radiation emitting semiconductor device comprising:
- an n-type body having a surface and a first end spaced apart from a second end;
- a first contact electrically connected to the first end of the n-type body;
- a second contact electrically connected to the second end of the n-type body;
- a plurality of generally parallel p-type conductive strips which are generally parallel to the surface of the n-type body and extend in a direction generally perpendicular to a direction from the first contact to the second contact;
- and
- a third contact electrically connected to the plurality of generally parallel p-type conductive strips.
