Investigation of Thermal Properties of β-Ga 2 O 3 Nanomembranes on Diamond Heterostructure Using Raman Thermometry
The β -Ga 2 O 3 nanomembrane (NM)/diamond heterostructure is one of the promising ultra-wide bandgap heterostructures that offers numerous complementary advantages from both materials. In this work, we have investigated the thermal properties of the β -Ga 2 O 3 NM/diamond heterostructure with three...
