ABSTRACT
The surface state density distribution Nss at an InP-Al2O3 interface beneath the gate electrode was obtained by applying the charge pumping measurement technique to the n-channel inversion-mode Al2O3-InP metal-insulator-semiconductor field-effect transistors. The observed Nss versus energy curve was U shaped spreading over the energy between the conduction-band edge and 1 eV above the valence-band edge. The result was in good agreement with that obtained from the capacitance-voltage curves of the metal-insulator-semiconductor diode by the Terman method.
