Sažetak
Thin films comprising three-dimensional germanium (Ge) quantum dot lattices formed by nitrogen assisted magnetron sputtering deposition in alumina matrix have been deposited using magnetron sputtering deposition. We have investigated how deposition conditions affect structural properties and the quantum confinement effect. In quantum- confined semiconductors, it is possible that multiple exciton generation (MEG) would occur. Multiple exciton generation is the process where multiple pairs of electrons and holes are generated after the absorption of a single photon. This process could be particularly beneficial for solar cells where they have the potential to increase the photocurrent significantly. In this work, we have shown how the optical and electrical properties of the films, especially their photo- induced current, and quantum efficiency can be modulated by changing the deposition conditions. Moreover, a significant photo-response and effect of multiple exciton generation effects is observed.
