CuBiSeCl2 may be particularly suited to the deposition of orientated thin films as a result of the effects of preferred orientation. Analysis of PXRD data measured on CuBiSeCl2 powder and pellets in reflection geometry reveals that CuBiSeCl2 particles preferentially orient in the [h00] and [00l] directions (S24), such that the [0k0] direction is oriented parallel with the surface normal direction, supported by refining the March-Dollase parameters using the Rietveld method. The preferred orientation of CuBiSeCl2 powders and pellets can be attributed to the needle-like particles observed in TEM images (S18) and during pellet pressing these needles align such that the ac plane is parallel to the pressing direction.
