설명

일반 설명

Tellurium dioxide (TeO₂) is a ceramic material that can be used as a semiconducting oxide. It has a wide band gap and high mobility as determined by density functional theory (DFT) calculations. In bulk quantity, it exists in two polymorphs which include tetragonal α-TeO₂ and orthorhombic β-TeO₂.

애플리케이션

TeO₂ can be potentially used in medical imaging and industrial monitoring processes.
