Motivated by the synthesized Cu 4 Ti Se 4 with ultralow room-temperature thermal
conductivity [Angew. Chem., Int. Ed. 60, 9106 (2021)], we systematically investigate its …

Structural non-centrosymmetry in semiconducting organic–inorganic hybrid halide
perovskites can introduce functionalities like anomalous photovoltaics and nonlinear optical …

Chemical bonding present in crystalline solids has a significant impact on how heat moves
through a lattice, and with the right chemical tuning, one can achieve extremely low thermal …

We report first-principle calculations of the recently synthesized Pb-free double perovskite
Cs2PtI6, which we found to have the potential to be an excellent thermoelectric material …

As the periodic atomic arrangement of a crystal is made to a disorder or glassy-amorphous
system by destroying the long-range order, lattice thermal conductivity, κL, decreases, and …

Perovskite materials have attracted much attention in various optoelectronics applications
such as solar cells, light-emitting diodes, and photodetectors. Compared to multicrystalline …

Thermoelectric copper selenides are highly attractive owing to not only their constituent
nontoxic, abundant elements but also their ultralow liquid-like lattice thermal conductivity …

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 …
