- Abstract
- The influence of InAs orientations and high-k oxide deposition conditions on the electrical and
structural quality of Au/W/Al2O3/InAs metal-oxide-semiconductor capacitors was investigated
using capacitance-voltage (C-V) and x-ray photoemission spectroscopy techniques. The results
suggest that the interface traps around the conduction band edge are correlated to the As-oxide
amount, while less to those of As-As bonds and In-oxides. The quality of the deposited Al oxide
determines the border trap density, hence the capacitance frequency dispersion. The comparison of
different processing conditions is discussed, favoring a 350 C high-k oxide deposition on (111)B
substrates... (More) - The influence of InAs orientations and high-k oxide deposition conditions on the electrical and
