✦ Synopsis


InS films with compositions close to that of the In 2 S 3 compound were prepared by an airless spray technique from spray solutions with composition ratio y In 3 aS 2Γ€ varying from 0.43 to 0.6. The structure of these films was characterized by electron diffraction and electron microscopy, and their optical properties were studied on the one hand by spectrophotometric measurements, on the other hand by spectroscopic ellipsometry. The influence of the increase of the y ratio on the optical properties as well as of annealing treatments up to 500 C is described and discussed in terms of crystallinity improvement.

An ion beam technique has been developed that allows the preparation of bevels from semiconducting heteroepitaxial structures with smooth surfaces and very shallow angles between 0.1Γ„ and 0.001Γ„. The bevels are used for AES depth proÐling of heterostructures by the line scan technique. Comparison of
