- W2323250937 abstract "We have studied the electronic properties of $2Hensuremath{-}{mathrm{WSe}}_{2}$ intercalated with Cu using the full-potential linear-augmented plane-wave method as implemented in the WIEN97 code. Intercalating $2Hensuremath{-}{mathrm{WSe}}_{2}$ with Cu changes the electronic behavior from semiconducting to metallic. We present calculations of ${mathrm{Cu}}_{x}{mathrm{WSe}}_{2}$ for $x=0.5$ and 1.0. The copper-d partial density of states in ${mathrm{Cu}}_{x}{mathrm{WSe}}_{2}$ is similar to that in pure copper. As in the case of copper, the Cu d bands are flat and lie 2--4 eV below ${E}_{F}.$ Our calculations show that there is weak hybridization between the Cu states and W and Se states. We have also calculated the frequency-dependent dielectric properties of ${mathrm{Cu}}_{x}{mathrm{WSe}}_{2}$ with a view to ascertain the effect of copper intercalation on the optical properties." @default.
