Growth of Wide Band Gap II-VI Compound Semiconductors by Physical Vapor Transport [PDF]

open access: yes, 1995
The studies on the crystal growth and characterization of II-VI wide band gap compound semiconductors, such as ZnTe, CdS, ZnSe and ZnS, have been conducted over the past three decades. The research was not quite as extensive as that on Si, III-V, or even

Evidence of defect band mechanism responsible for band gap evolution in (ZnO)1−x(GaN)x alloys

open access: yes, 2019
It is known that (ZnO)1−x(GaN)x alloys demonstrate remarkable energy band bowing, making the material absorb in the visible range, in spite of the binary components being classical wide band gap semiconductors.
