The flexibility of hydride vapour phase epitaxy (HVPE) for fabricating
nanostructures is demonstrated by exemplifying three cases: (1) impro
vement of optical characteristics of wet etched wires after overgrowth
, (2) improvement of electrical characteristics of reactive ion etched
wires after regrowth and (3) fabrication of InP templates on GaAs sub
strate written previously with focused ion beam (FIB). (C) 1998 Elsevi
