Features of InP on Si Nanowire Growth
摘要
Abstract
The possibility of InP nanowhiskers growth from the saturated phosphorus and indium vapors with V/III ratio of 8–10 in a quasi-closed volume on (111) oriented silicon substrates with a natural oxide layer 2–2.5 nm has been demonstrated. The growth of InP nanowhiskers from Au-In-P catalytic droplets formed during the initial period is reported. Optical studies confirmed the formation of InP nanostructures upon the Si surface. The nanostructures exhibit a high doping level presumably with tin atoms.
