Abstract

Raman spectroscopy is used to characterize the microscopic bonding structure of a-SiGe:H alloys. Excess Ge-Ge bonding over what is predicted for random alloys is observed. Correlation between the degree of Ge-Ge clustering and the transport properties of the alloys is demonstrated. Implications of the experimental findings regarding improvement in the quality of the alloy material are discussed.
