Abstract: An infrared emitter, which utilizes a photonic crystal (PC) structure to produce electromagnetic emissions with a narrow hand of wavelengths, includes a semiconductor material layer, a dielectric material layer overlaying the semiconductor material layer, and a metallic material layer having an inner side overlaying the dielectric material layer. The semiconductor material layer is capable of being coupled to an energy source for introducing energy to the semiconductor material layer. An array of surface features are defined in the device in a periodic manner or quasi-periodic. The emitter device is adapted to emit electromagnetic energy having spectral characteristics determined by parameters of the periodically distributed surface features, the parameters including shape, size, depth, distribution geometry, periodicity, material properties and defects.

Abstract: A device made by a process of making strain-free, heavily carbon-doped p-type epitaxial layers for use in high performance devices and at least one such device so made. The process essentially includes the epitaxial deposition of a strain-free, carbon-doped p-type layer in a GaAs HBT device to form the base layer thereof in a manner that includes the balancing of the strain of the crystal lattice structure caused by the carbon doping by co-doping the base layer with an isovalent and isoelectric dopant. The co-doping also improves device performance. It also effects alloy hardening, which inhibits further defect formation, improves mobility and carrier lifetime of the base layer and, by narrowing the energy gap, it improves ohmic contact formation.
