An oxide semiconductor with a band gap of about 4.5-4.9 eV, even wider than SiC or GaN. Its crystals can be grown from the melt, and it is being researched as a next-generation power semiconductor material.
Field: Compound semiconductors
Ga2O3 has a bandgap of about 4.5–4.9 eV, wider than SiC or GaN, and an expected breakdown field of about 8 MV/cm, promising even higher voltage ratings and lower losses.
Which is a characteristic of gallium oxide (Ga2O3), under r…Even wider-gap Ga2O3 (about 4.8 eV) and diamond (about 5.5 eV) are called ultra-wide-bandgap semiconductors.
What is the general term for semiconductors with a larger b…This is also why Ga2O3 and diamond, with even larger Ec, are promising next-generation materials.
