Structural properties of single-phase films of κ-In[sub 2]Se[sub 3] and γ-In[sub 2]Se[sub 3] were investigated. Both films were polycrystalline but their microstructures differed considerably. The a-lattice parameter of κ-In[sub 2]Se[sub 3] has been measured. A comparison between these two materials indicates that κ-In[sub 2]Se[sub 3] has a significantly larger unit cell (Δc = 2.5 ± 0.2% and Δa = 13.5 ± 0.5%) and a structure more similar to the α-phase of In[sub 2]Se[sub 3].
