Band offset in semiconductor heterojunctions [PDF]

Journal of Physics: Condensed Matter, 2021
Semiconductor heterojunctions are widely applied in solid-state device applications, including semiconductor lasers, solar cells, and transistors. In photocatalysis they are of interest due to their capability to hinder charge carriers' recombination. A key role in the performance of heterojunctions is that of the alignment of the band edges of the two

CdTe-InSb Heterojunctions

Physica Status Solidi (a), 1980
An investigation is made of the properties of the contact CdTe–InSb realized by deposition of InSb on the etched surface of n-type CdTe single crystals and annealing. The profile of the elemental composition of the contact obtained by secondary ion mass spectrometry (SIMS) shows that certain interfacial chemical reactions do occur. The results obtained

Defective heterojunction models

Surface Science, 1986
Fermi-level pinning behavior has been observed at the free surface, oxide interface, metal interface, MBE grown surface, stop-regrown homojunction, and misfit-dislocation pinned heterojunction of GaAs. Theories of such behavior are numerous and disparate.
