The recent re‐emergence of halide perovskites has received escalating interest for
optoelectronic applications. In addition to photovoltaics, the multifunctional nature of halide …

Significant progress has been made in the past two decades about the micro/nanoscale
heat conduction. Many computational methods have been developed to accommodate the …

Controlling the flow of thermal energy is crucial to numerous applications ranging from
microelectronic devices to energy storage and energy conversion devices. Here, we report …

Aside from photovoltaics, metal-halide perovskite semiconductors have also emerged as an
attractive platform for LEDs and even lasers. For all of them, performance and operational …

In addition to the broadly anticipated use of metal halide perovskites in photovoltaics and
light-emitting devices, they also hold a great promise as cost-effective thermoelectrics, as …

Metal halide perovskites have emerged as promising photovoltaic materials, but, despite
ultralow thermal conductivity, progress on developing them for thermoelectrics has been …

Fundamental understanding of the correlation between chemical bonding and lattice
dynamics in intrinsically low thermal conductive crystalline solids is important to …

Net zero refers to the balance of the amount of greenhouse gas emissions produced and the
amount removed from the atmosphere, and many companies and states have committed …

We highlight the importance of carrier–phonon coupling in inorganic lead halide perovskite
nanocrystals. The low-temperature photoluminescence (PL) spectrum of CsPbBr3 has been …

We review our recent development of a first-principles lattice dynamics method that can treat
anharmonic effects nonperturbatively. The method is based on the self-consistent phonon …
