摘　　要：Large quantities of metal indium single-crystalline wires with diameters ranging from tens of nanometres to a few micrometres were synthesized on Si substrates. Unlike traditional methods for the fabrication of nanowires or nanorods, liquid indium was squeezed out of the pores and cracks from porous an InAlN layer to form the wires. Continuous pushing out of liquid metal indium under strength, lowering of liquid-solid interfaces and the confinement of the cracks all contribute to the growth of indium wires. Our experiments have shed some light on the possibility of synthesizing large quantities quasi-1D nano/sub-micron structures with specified cross-sectional geometry using the similar method.Large quantities of metal indium single-crystalline wires with diameters ranging from tens of nanometres to a few micrometres were synthesized on Si substrates.
