Abstract
We introduce an experimental technique which allows the characterization of domains in nonmagnetic cubic crystals of the zinc-blende type. The technique exploits the optical anisotropy of cubic crystals near an excitonic resonance which translates to a dependence of the reflected light polarization on crystal orientation. We demonstrate sub 10 mu m domains on the [110] surface of a high quality, homoepitaxially grown ZnSe film. (C) 1998 American Institute of Physics.
