Spatial composition fluctuations in blue-luminescent ZnCdO semiconductor films grown by molecular beam epitaxy
The optical and structural properties of textured ZnCdO films that exibit a newly found distinct blue luminescence have been investigated. Microscopic compositional fluctuations of Cd, associated with hexagonal structures were observed. Models for the blue-luminescence process are proposed. (C) 2002 Elsevier Science B.V.
