Heteroepitaxial stabilization of α-phase Ga2O3 thin films with superior thermal conductivity compared to β-phase

Gallium oxide (Ga2O3) is an emerging ultrawide-bandgap semiconductor for next-generation power electronics. However, the relatively low thermal conductivity of the technologically most promising β-Ga2O3 phase poses a major challenge for thermal management in high-power devices. The metastable corund...
