We show that spin–orbit coupling in methylammonium lead-iodide perovskite generates Fermi surfaces of peculiar topology: for the low charge-injection regime of interest for photovoltaic applications, the Fermi surfaces are donuts (ring tori), which evolve into apples (spindle tori) as the band population is raised, with a vortex spin texture that indicates the dominance of the Rashba effect. This ...

- ... The fundamental properties of lead halide perovskites, rivaling those of conventional semiconductors, make these systems attractive not just for solar cells but also for a broader playground of energy and nanotechnology applications. The recently measured ultralow thermal conductivity of the perovskites suggests the possibility of high thermoelectric efficiency and the possible use of the perovski ...
