Epitaxial growth of low threading dislocation density InSb on GaAs using self-assembled periodic interfacial misfit dislocation
Highlights
•High-quality InSb was grown on GaAs by MBE using a “buffer-free” method.
•The strain energy is relieved by interfacial misfit dislocations observed by TEM.
•The type and separation of dislocations are [...]

GaAs pn diodes with heavily carbon-doped p-type GaAs grown by MOMBE were fabricated. The I-V and C-V characteristics were not significantly affected by the hole concentration of the p-GaAs although a lattice mismatch at the junction generates misfit dislocations. A good I-V characteristic with [...]
