摘要
Capacitance-voltage measurements were made on Cr-gated metal-oxide-silicon structures with ultrathin (similar to 30 Angstrom) thermal oxides. Using an empirical model, activation energies for the passivation of the P-b center were determined and found to be dependent on the charge state of the defect. Depassivation was found to occur at positive gate biases. (C) 2000 American Institute of Physics. [S0021-8979(00)06810-9].
