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.
