Innovative technology assessment and crystalline quality optimization of columnar β-Ga ₂ O ₃ crystal growth were performed via an EFG method.

This work investigated the blue color center in β-Ga₂O₃ crystals grown by the EFG and obtained an effective method to eliminate it.

A novel semi-insulating Co:β-Ga₂O₃ single crystal was designed and grown; the Co:β-Ga₂O₃-based device is endowed with great operating stability at high temperatures and under extreme conditions.

The β-Ga ₂ O ₃ (011) plane could be a potential substrate orientation for power devices because it avoids a kind of dislocation which leads to leakage current and breakdown of power devices as the dislocations propagate parallel to the (011) plane.
