Paper Abstract

An etch process was developed to determine the dislocation density on <111>B - Hg1-xCdxTe-epilayers grown by liquid phase epitaxy from a tellurium-rich solution. A correlation between the etch pit density and the Cd1-yZnyTe-substrate material properties is found. Additionally the yield of photovoltaic diode performance strongly depends on the value of these measured dislocation densities. This method acts as a pass/fail evaluation for the epilayers used in our infrared device fabrication.
