Flexible and on wafer hybrid plasma-semiconductor transistors

Preferred embodiment flexible and on wafer hybrid plasma semiconductor devices have at least one active solid state semiconductor region; and a plasma generated in proximity to the active solid state semiconductor region(s). A preferred device is a hybrid plasma semiconductor device having base, emitting and microcavity collector regions formed on a single side of a device layer. Visible or ultraviolet light is emitted during operation by plasma collectors in the array. In preferred embodiments, individual PBJTs in the array serve as sub-pixels of a full-color display.
