摘要
The native oxide was allowed to grow at room temperature on bulk InSb prior to deposition of indirect plasma enhanced chemical vapour deposited silicon dioxide. Capacitance characterization of metal-insulator-semiconductor structure samples showed superior results when contrasted with native oxide-free specimens. Both p-type and n-type InSb samples were studied and surface state densities decreased following oxidation to approximately 3 x 10(11) cm-2 eV-1 while hysteresis decreased significantly. We conclude that preservation of the native oxide is critical for good dielectric-semiconductor interfaces on InSb, especially p-type material.
