Abstract

The HRXRD and FTIR characterization of HgCdTe epilayers grown by vertical Dipping Liquid Phase Epitaxy was analyzed to indicate the presence of <2 μm low-x HgCdTe over layer. A higher angle shoulder in HRXRD rocking curve and a graded cut-on as well as a double fringe pattern in FTIR was observed. Removal of ~2 μm surface layer by chemical etching improved the FTIR and HRXRD curves.
