Effect of V/III ratio on the structural quality of InAs nanowires

Abstract

In this study, the effect of V/III ratio on the structural quality of Au-catalyzed InAs nanowires grown by molecular beam epitaxy is investigated. It is found that, by tuning the V/III ratio, the structural quality of InAs nanowires can be controlled, and defect-free wurtzite structured InAs nanowires have been achieved under low V/III ratio growth.
