Characterization of CdS0.9Se0.1 Powder by Scanning Transmission Electron Microscopy
n-type CdS0.9Se0.1 powder was produced by mixing and annealing of CdS and Se powders that were prepared by a reflux method using Cd(CH3CO)2 2H2O, thiourea and ethylene glycol, and by a solution method using SeO2, ethylene glycol and NaBH4, respectively. The product was supposed to be crystalline CdS...

| Summary: | n-type CdS0.9Se0.1 powder was produced by mixing and annealing of CdS and Se powders that were prepared by a reflux method using Cd(CH3CO)2 2H2O, thiourea and ethylene glycol, and by a solution method using SeO2, ethylene glycol and NaBH4, respectively. The product was supposed to be crystalline CdS0.9Se0.1 powder from simulation of X-ray diffraction pattern using CaRine 3.1 program and JCPDS card of CdS (space group P63mc). Analytical electron microscopy revealed that Cd, S and Se atoms were homogeneously distributed in the powder, which was composed of particles as fine as a few ten nm and in a single crystalline phase, supporting the formation of CdS0.9Se0.1. This CdS0.9Se0.1 powder is expected to be used as n-type thermoelectric materials. |
