摘要:
AbstractRaman scattering measurements in the tetragonal Cd3As2single crystals are carried out at temperatures of 300 and 77 K. The spectra obtained are interpreted in terms of phonon‐electron and electron‐electron interactions. The features in the low‐frequency interval are due to contributions from phonon and single particle scattering. The electronic RS involving intra‐ and interband excitations is dominant at frequencies higher than 80 cm−1. The resonant enhancement of the band at 300 cm−1arises from the incident light frequency being in the vicinit
