CdS/CdSe lateral heterostructure nanobelts by a two-step physical vapor transport method

Abstract:

The two-dimensional heterostructure nanobelts with a central CdSe region and lateral CdS structures are synthesized by a two-step physical vapor transport method. The large growth rate difference between lateral CdS structures on both (0001) sides of the CdSe region is found. The growth anisotropy is discussed in terms of the polar nature of the side (0001) surfaces of CdSe. High-resolution transmission electron microscopy reveals the CdSe central region covered with non-uniform CdS layer/isl...
