In our investigations, Au, Al, Ni, Pt, Ti, and combinations thereof were deposited on InP and InGaAs by e-beam evaporation to form Schottky contacts. The Schottky-barrier heights of these diodes determined by forward I–V and (or) reverse C–V measurements lie between 0.38–0.48 eV. To increase the Schottky-barrier height, a strained GaxIn1−xP layer was inserted between the electrode metal(s) and the semiconductor. This material, which has a band-gap larger than InP, was grown by gas-source molecular beam epitaxy. The Schottky-barrier heights, which generally depend on the gallium fraction, x, and the thickness of the strained GaxIn1−xP layer, increase and are in the range of 0.56–0.65 eV in different contact schemes.

AbstractThe quality of heteroboundaries and optimal conditions for epitaxial growth are critical parameters for obtaining low leakage currents of heterobarrier varactors in the InGaAs/InAlAs/AlAs material system. Grown by molecular-beam epitaxy, three-barrier heterobarrier varactor structures adjacent to InAlAs/AlAs/InAlAs barrier layers by additional mismatched InGaAs layers subjected to compressive stress show, under optimal epitaxy conditions, extremely low levels of leakage current density (not more than 0.06 A/cm^2 at a voltage of 5 V and 85°C) with relatively thin AlAs inserts (with a thickness of 2 nm).
