Elevated temperature dependence of the anisotropic visible-to-ultraviolet dielectric function of monoclinic beta-Ga2O3

A. Mock, J. VanDerslice, R. Korlacki +2

We report on the temperature dependence of the dielectric tensor elements of $n$-type conductive $\beta$-Ga${}_2$O${}_3$ from 22${}^{\circ }$C-500${}^{\circ }$C in the spectral range of 1.5~eV--6.4~…
