Abstract
A non‐alloyed ohmic contact to n‐type GaAs has been demonstrated. The technique of solid phase epitaxy through a transport medium has been used to obtain a metal/Ge(n+, epi)/GaAs(n, 〈100〉) heterostructure. The resulting contact displays a smooth surface and low contact resistivity (∼10−6–10−5 Ω cm2) when compared with standard Au‐Ge contacts on n‐GaAs with similar doping concentrations (∼1018/cm3).Keywords
