Webb25 nov. 2024 · 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.
