Application
- Hafnium(IV) oxide: Utilized predominantly in the semiconductor industry, Hafnium(IV) oxide offers excellent thermal and chemical stability, which makes it suitable as a high-k gate dielectric material in metal-oxide-semiconductor (MOS) devices. Its application has become increasingly important with the miniaturization of electronic components, aiding in the enhancement of transistor performance without further reducing the component size. This role is critical in the development of more efficient, faster computing technologies (Sigma-Aldrich, CAS 12055-23-1).
