ZnO (Zinc oxide). by Alexander Glavtchev. Why is ZnO interesting?. Widely used: medicinal purposes (colds, rashes, antiseptics, sunscreen lotions) used in manufacturing of rubber as rubber cure (or as filler) pigment for paints and coatings
ZnO (Zinc oxide)
Melting Point: 1975 °C
High electron mobility: >100cm2/Vs
High exciton binding energy: ~60meV (electron-hole binding energy)
Direct bandgap: 3.3eV
The output amplitude is related to the input signal by:
Lithium niobate (LiNbO3) and Lithium tantalate (LiTaO3) are currently two very-widely used piezoelectric crystals due to their high piezoelectric strain coefficients.
