摘要
We performed model calculations of Raman responses for multiband two-dimensional superconductors. The multiband effects of screening in the A(1g) symmetry channel were investigated analytically and numerically for a band-structure model mimicking angle-resolved photoemission spectroscopy data on iron-pnictide materials. An acceptable agreement between our model calculations and recent experimental data is demonstrated by modification of the band-structure parameters.
