Ion Beam Induced Epitaxial Regrowth and Interfacial Amorphization of Compound Semiconductors

A review of MeV-ion beam induced crystallization (IBIEC) and interfacial amorphization (IBIIA) in III-V compounds (GaAs, InAs, GaP, InP) is given. The kinetics of IBIEC and IBIIA is studied as a function of th...

Ion Beam Induced Epitaxial Crystallization of Single Crystalline 6H-SiC

For the first time, ion beam induced epitaxial crystallization (IBIEC) has been found in SiC. The effect of 300 keV Si⁺ irradiation through an amorphous surface layer in single crystalline 6H-SiC at 477±5°C has b...
