Abstract: | Nanocrystalline CdSe films were grown onto glass substrates by the chemical bath method. Different constant deposition temperatures (Td) were employed in the range 4-65 degreesC. Average grain size (GS) increased monotonically with Td, reaching saturation at similar to 65 degreesC. The GS values were in the interval 5-16 nm. At low T-d values (4-15 degreesC) the structural phase was hexagonal wurtzite (W). for intermediate values. a wurtzite and zincblende (ZB) mixture of phases was found, and at high T-d (65 degreesC) only cubic ZB phase was present in the layers. The variation of the bandgap as a result of the structural phase change and quantum confinement is studied. |
