How the phosphorus chains impact on the vibrational properties of diphosphides ZnP2 and CdP2 at low temperatures
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2016, Vol 19, Issue 4
Abstract
The temperature dependence of the vibrational modes in the diphosphides ZnP2 and CdP2 has been studied by employing IR reflectance spectroscopy within the 4…300 K temperature range in the polarized radiation. It has been demonstrated that decreasing the bond distance in the phosphorus chain at low temperatures causes an additional amount of anharmonicity of the corresponding modes, which is manifested in more pronounced temperature dependences of their frequencies and damping coefficients.
