We describe a new family of clocked logic gates based on the resonant-tunneling diode (RTD). Pairs of RTDs form storage latches, and these are connected by networks consisting of field-effect transistors (FETs), saturated resistors, and RTDs. The des

Geiger-mode (photon-counting) operation at 1.06 μm has been demonstrated with InGaAsP/InP avalanche photodiodes operated at room temperature. A photon detection efficiency of 33% was measured on uncoated detectors, representing an internal avalanche

Device-quality layers were regrown on GaAs wafers by molecular-beam epitaxy over conductive pregrown areas and on selectively patterned high-resistivity areas formed by oxygen implantation. The regrowth over both areas resulted in comparable device-q

A general technique has been demonstrated at microwave and submillimeter-wave frequencies for photoconductive sampling in the frequency domain using photomixers and continuous-wave laser diodes. A microwave version in which two photomixers were coupl

A novel technique of integrating resonant-tunneling diodes (RTDs) with pseudomorphic high-electron-mobility transistors (pHEMTs) is demonstrated. A proton was implanted through the pHEMT layers to convert the RTD structure underneath to a high-resist
