dc.description.abstract In0.53Ga0.47As metal-oxide-semiconductor (MOS) capacitors with an Al2O3 gate oxide and a range of n and p-type In0.53Ga0.47As epitaxial concentrations were examined. Multi-frequency capacitance-voltage and conductance-voltage characterization exhibited minority carrier responses consistent with surface inversion. The measured minimum capacitance at high frequency (1 MHz) was in excellent agreement with the theoretical minimum capacitance calculated assuming an inverted surface. Minority carrier generation lifetimes, sg, extracted from experimentally measured transition frequencies, xm, using physics based a.c. simulations, demonstrated a reduction in sg with increasing epitaxial doping concentration. The frequency scaled conductance, G/x, in strong inversion allowed the estimation of accurate Cox values for these MOS devices. en
