Abstract
InxGa1¿xAs layers with In concentrations up to 35% have been grown on GaAs substrates by MOCVD using a GaAs/InxGa1¿xAs superlattice with graded layer thicknesses to accommodate the lattice mismatch. 105 ¿m-diameter PIN diodes fabricated from this material have leakage currents below 1 nA at ¿ 10 V, comparable to devices from lattice-matched material on InP substrates.
