Electrolyte electroreflectance of HgCdTe at low temperatures.

Electrolyte electroreflectance measurements in ethanol/lithium perchlorate solutions over the temperature range 300–156 K have been used to derive the temperature dependence of the E1 transition of Hg1-xCdxTe (x=0.23–0.36). The temperature coefficient dE1/dT derived by third derivative line-shape fitting (6.6±0.5×10-4 eV K-1) is considerably higher than values reported previously in the literature. [ABSTRACT FROM AUTHOR]
