摘要
Communication: The first preparation of transparent conducting Cd2SnO4 thin films by a simple MOCVD process is described. As-deposited films using Cd(hfa)(2)(TMEDA) (Figure), at 365 degreesC are found to be highly crystalline with a relatively wide range of grain size of 100-300 nm. XRD indicates a cubic spinel CdSnO4 crystal structure and the possible presence of a small amount of CdO. The films exhibit conductivities of 2170 S/cm and a bandgap of 3.3 eV, rivaling those of commercial tin-doped indium oxide.
