Abstract / Description:We report the isotope effects of copper and bromine on the gap
of CuBr, and that of copper on the gap of CuI. The measured
isotope effects reveal an anomalous negative shift with
increasing copper mass for the three halides. These results
allow us to understand the anomalous temperature dependences of
the band gap E-0 in the copper halides, which we report in the
case of CuI. Similarities to the behavior observed for the
copper and silver chalcopyrites are also pointed out.
