Monolithic resonant-tunneling-diode (RTD) relaxation oscillators are fabricated. The highest repetition rate of this pulse generator is 6.7 GHz with a pulse width of approximately 60 ps. Oscillators with an RTD connected to an off-chip transmission l

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

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 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

Resonant-tunneling diodes (RTDs) with a new planar configuration have been fabricated with a new self-aligned process that is compatible with that of silicon integrated-circuits technology. The size of the RTD is determined by a shallow boron implant

Resonant-tunneling diodes (RTDs) have demonstrated oscillation frequencies above 400 GHz and switching speeds of 2 ps, establishing them as the fastest all-electronic switches at room temperature. This high speed, together with reasonable impedance l

Superconducting tunnel junctions have been used as the nonlinear element for mixing at a signal frequency of 115 GHz. The experimental results are compared with predictions of a theoretical analysis based on the quantum theory of mixing of J. R. Tuck
