| Abstract
| - In this paper, multilayer superstructures of single-crystalline ZnTe nanowire films have been prepared through a new growth process: well-aligned ZnTe nanowires congregate into nanowire film. The growth process takes place discontinuously and consequently produces many layers of aligned ZnTe nanowire superstructures. These interesting findings are apparently different from the conventional vapor−liquid− solid (VLS) process but following a new multiple nucleation growth model. The intriguing growth mode of multilayer superstructures of aligned ZnTe nanowires may enrich our understanding of the growth mechanism of nanowires. The photoluminescence spectrum of the obtained multilayer ZnTe NWs superstructures exhibits strong free exciton emission peak and relatively weak Ia line, indicating that the layers are of high quality, which may have potential applications in nanodevices.
