摘要

Selective MBE growth of an array of < -110 > -oricnted GaAs ridge QWRs was attempted on pre-patterned (001) substrates. Arrow-head shaped GaAs QWRs were selectively formed on the top (113)A facets of GaAs ridge structures. The underlying growth mechanism was clarified, and based on this, the wire width could be kinetically controlled by the growth process.
