Query: Electron effective mass in Sn-doped monoclinic single crystal
  $\beta$-gallium oxide determined by mid-infrared optical Hall effect   The isotropic average conduction band minimum electron effective mass in
Sn-doped monoclinic single crystal $\beta$-Ga$_2$O$_3$ is experimentally
determined by mid-infrared optical Hall effect to be $(0.284\pm0.013)m_{0}$
combining investigations on ($010$) and ($\bar{2}01$) surface cuts. This result
falls within the broad range of values predicted by theoretical calculations
for undoped $\beta$-Ga$_2$O$_3$. The result is also comparable to recent
density functional calculations using the
Gaussian-attenuation-Perdue-Burke-Ernzerhof hybrid density functional, which
predict an average effective mass of $0.267m_{0}$ (arXiv:1704.06711
[cond-mat.mtrl-sci]). Within our uncertainty limits we detect no anisotropy for
the electron effective mass, which is consistent with most previous theoretical
calculations. We discuss upper limits for possible anisotropy of the electron
effective mass parameter from our experimental uncertainty limits, and we
compare our findings with recent theoretical results.
