Ab-initio transport, simple and fast.

Phoebe is an open-source code for the ab-initio computation of electron and phonon transport properties of crystalline materials.

It is designed to take advantage of HPC systems via MPI-OpenMP hybrid parallelism, memory-distributed computing via ScaLAPACK, and GPU accelerated calculation of scattering rates.

Phonon linewidths projected onto dispersion of silicon
Electron-phonon limited conductivity with the Wigner transport equation
Electron-phonon linewidths for GaN along its band structure
Resistivity of n-type (CoSb3) skutterudite, for which the RTA (dark blue triangles) and iterative (light blue 'x's) perform similarly.
RTA phonon lifetimes of GaN, where colors from blue to green represent different phonon branches of increasing energy.
Lattice thermal conductivity of GaN along the 'a' crystal axis using the RTA, variational, and relaxons solvers.
