Hybrid Halide Pervoskites​​

Organic–inorganic hybrid halide perovskites have recently emerged as prominent candidates for optoelectronic applications due to their excellent material properties. In addition to their photonic applications such as solar cells and light emitting diodes (LEDs), we are also studying their dimensional reduction and new opportunities for electronic device applications.
