SURFACE STATES IN THE SPHERICAL NANOCRYSTALS CDSE, CDTE
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2018, Vol 15, Issue 1
Abstract
The energy of surface states has been define, which causes by the polarization charges on the interfaces, by numerical methods. It has been found conditions of their existence. Especially, it has been show that for heterosystems with large difference between dielectric permittivities the according surface states exist in the large nanocrystal size range. It has been obtain, that the nanocrystal size increase, every energy level, which splits from the continues spectrum, in the quantum well can become the surface state in the polarization quantum well. It has been define, which states become the surface states. The obtained results have been compared with those ones for different nanocrystals.
