By systematically exploring the parameter space accessed by MBE and MOCATAXY, phase-pure $\\alpha$-Ga$_2$O$_3$(10$\\bar{1}$0) and $\\alpha$-(In$_x$Ga$_{1-x}$)$_2$O$_3$(10$\\bar{1}$0) thin films are realized. The presence of In on the $\\alpha$-Ga$_2$O$_3$ growth surface remarkably expands its growth window far into the metal-rich flux regime and to higher growth temperatures.
