Temperature-dependent Raman-active phonon modes and electron−phonon coupling in β-Ga2O3 microwire

The lattice vibration and electron-phonon coupling (EPC) in β -Ga _2 O _3 microwire are systematically investigated. The β -Ga _2 O _3 microwire that is (020)-oriented shows 14 Raman peaks, with all their FWHM narrower than those of (100)-oriented β -Ga _2 O _3 bulk single crystal. As the temperatur...
