High yield-low temperature growth of indium sulphide nanowires via chemical vapor deposition
(2010)Indium sulphide nanowires (NWs) have been grown on Si via the reaction of In and InCl3 with H2S using chemical vapor deposition at temperatures as low as 250 °C. We find that the growth of InxSy NWs via the direct reaction ...
