O projektu

The proposed project focuses on the investigation of novel high-stable monocrystalline perovskites for photosensing in ultraviolet, visible and alternatively in infrared region of electromagnetic radiation. Therefore the research will be targeted to explore a new type of leadhalide perovskite single crystals like “core-shell” type of crystal and doped standard type of monocrystals. The ability of sensing of as-prepared monocrystals will be characterized by method of temperature-modulated space-charge-limited currents, which enables us to analyse the density of charge carrier traps in bandgap of measured materials. The influence of different crystal diameters and different biases and/or frequencies applied on measured responses will be studied as well. At the end of the project, monocrystalline perovskites with higher long-term stability for photodetectors with sensing at low radiation intensities will be suggested.
