Cscl band gap

WebApr 19, 2024 · Comparing with the CsCl structure results, the L(ω) function with RS has more peaks, and this is related to the differences in energy band gap region. Maximum energy loss occurs when the real part of the dielectric function ε 1 (ω) is minimum, and when there is a rapid decrease in reflectivity R (ω). http://www.chinashippingna.com/
