A chemical solution transport (CST) growth has been proposed for the formation of CdS nanowires from the solution phase. In the growth process, PAA layers overcoat the nanowires, which serve to terminate the growth in the lateral direction. Consequently, continuous single-crystalline nanowires with great aspect ratios and smooth morphology were obtained 关键词: cadmium compounds;crystal growth from solution;crystal morphology;II-VI semiconductors;lattice constants;nanostructured materials;particle size;semiconductor growth;wide band gap semiconductors;X-ray diffraction;chemical solution transport mechanism;one-dimensional growth;CdS nanowires;thermal treatment;Cd2+-dispersed polyacrylamide;ethylenediamine solution;thiourea;sealed system;CST;growth process;lateral direction;continuous single-crystalline nanowires;aspect ratios;smooth morphology;solution phase growth;170 degC;4 day;CdS
