Zinc
Incorporation via the Vapor-Liquid-Solid Mechanism into InP Nanowires
JACS 131 (2009) 4578-4579
Abstract:
We report the incorporation of zinc atoms into vapor-liquid-solid grown
indium phosphide nanowires via a gold catalyst particle. We demonstrate
this by synthesizing axial pn-junctions, chemically etching them, and
fabricating electrical contacts in a vertical configuration. Electrical
measurements show clear diode behavior. Control of dopant incorporation
is crucial for future applications and will eventually lead to full
freedom of design.
