Abstract

The photoconductance method was used to determine the Al mole fraction in both bulk AlGaN and AlGaN/GaN heterostructure samples. The results were consistent with those obtained by a much more elaborate photoluminescence measurement. The photoconductance method is deemed a simple and convenient way to estimate the Al mole fraction in AlGaN.
