| Abstract: | The electronic band gap of SrSe, in the CsCl-stuctured phase, was measured to 42 GPa via optical absorption studies. The indirect electronic band gap was found to close monotonically with pressure for the range of pressures studied. The change in band gap with respect to pressure, dEgap/dP, was determined to be −6.1(5)×10−3 eV/GPa. By extrapolation of our line fit, we estimate band gap closure to occur at 180(20) GPa. |
