Abstract
Semiconductor devices having conductive floating gates superimposed on and/or embedded within a conducting channel for managing electromagnetic radiation in the device. The conductive floating gates can comprise a one- or two-dimensional array of asymmetric structures superimposed on and/or embedded within the conducting channel. The conductive floating gates can comprise NbN, TaN, TaN, NbN, WN, or MoNor any transition metal nitride compound. The device can include a plurality of conductive floating gates on a rear surface of a barrier layer, wherein each of the conductive floating gates might be separately biased for individual tuning. Antennas for capturing or emitting THz or sub-THz radiation could be attached to the device contacts. Terahertz or infrared radiation could be manipulated by driving a current through the conducting channel into a plasmonic boom regime. Additional manipulation of the electromagnetic radiation could be achieved by having antennas with an appropriate phase angle shift.
