In a method of forming a II-VI compound semiconductor thin film on an InP substrate, a layer of III-V compound semiconductor mixed crystal is first formed on the InP substrate. The desorption rate of a group V element constituting the III-V compound semiconductor mixed crystal at a decomposition tem...
