Abstract

original image

The chalcopyrite-like structure of Cu2MSnQ4 is an ordered tetrahedral array of flattened CuQ4 and undistorted MQ4 and SnQ4, with a low lattice thermal conductivity. The [Cu2Q4] tetrahedral layers are electrically conducting, and the [SnMQ4] layers are electrically insulating.
