Abstract
A number of features characteristic of different thin-film analytical methods are reviewed and evaluated. The principles, approaches for quantification and prominent problems of the most commonly used methods (ESCA, AES, SIMS, LEIS, RBS and NRA) are discussed. Evaluation of the specialadvantages and disadvantages of the different methods points out the need for a synergetic multi-method approach in thin-film analysis.

This review was received in June 1983.
