“Electron-hole separation in type II nanoscale heterostructures built of II-VI semiconductors”
The staggered band alignment characteristic for a type II semiconductor heterostructure leads to a spatial separation of conduction band electrons and valence band holes at the interface. The first part of the seminar will be devoted to our recent development of ZnTe/CdSe core/shell nanowires, in which the spatially indirect optical transition appears in the near infrared spectral range [1]. In the second part it will be demonstrated how the electron-hole spatial separation affects the emission from individual (Cd,Se)Te quantum dots embedded in ZnTe matrix [2].[1] P. Wojnar et al.
