  We performed ab-initio driven density functional theory-based high throughput
computations to search for materials with low thermal conductivity and high
thermal transport anisotropy. We shortlisted a pool of 429 stable ternary
semiconductors from the Materials Project and obtained phonon thermal
conductivity by solving the Boltzmann transport equation on 225 materials. We
found the lowest thermal conductivity of 0.16 W/m-K in SbRbK 2 and 40 materials
with a thermal conductivity lower than 1 W/m-K at 300 K. For anisotropic
thermal transport, we have identified six materials with anisotropy larger than
5 and 20 with thermal transport anisotropy higher than the largest reported
literature value.
