Owing to high quantum yields, large absorption
cross-section, excellent carrier transport performance and
narrow-band emission, inorganic lead-halide perovskite
semiconductors have received increasing attention for their
applications in solar cells, LEDs, laser devices, etc.
Understanding the physical origin of temperature dependence of
bandgap in inorganic lead-halide perovskites is essential and
important.
