We report single-wavelength ellipsometric measurements of the complex index of refraction of rough Zn<sub>3</sub>As<sub>2</sub> films on InP substrates. What we believe to be a novel technique, based on surface roughness measurements by atomic-force microscopy, is discussed to extract useful information from the ellipsometry results. The anticipated presence of a thin oxide layer is confirmed by Auger electron spectroscopy.
