Thin films of cubic In2Se3 have been grown by low-pressure metal-organic chemical vapor deposition (LP-MOCVD) using the novel precursor In(Se2CNMe n-hexyl)(3). The precursor was prepared from carbon diselenide and a modified experimental procedure for the synthesis of CSe2 is described. Films were grown on glass and InP(111) between 450 and 500 degrees C, and characterized by X-ray diffraction and scanning electron microscopy.
