About these proceedings

Introduction

Conferences on the Physics of Selenium and Tellurium were held in 1964 in London, 1967 in Montreal, and eight years ago, 1971, in Pont-a-Mousson. The last conference was noteworthy because of two facts: For crystalline Te and Se a high level of results was achieved and, further, it was possible to outline the focal points for continuing research work. These points were mainly to explore. the electronic structure of trigonal Se and Te and of the hypothetic~l cubic limit of these materials. To im­ plement such study, progress in band structure calculations was necessary. In addition, a consistent analytical description of the bands near the va­ lence band conduction band gap was required with the aim to understand the semiconducting properties, mainly magnetotransport and magnetooptical ef­ fects of band electrons and of impurities. Further questions concerned the influence of defects, such as dislocations, on transport properties and, finally, a concluding description of lattice dynamics of trigonal Se and Te, based on theoretical and experimental work, such as neutron diffraction and optical measurements. Besides the listing of this future research program it became obvious that more detailed work on the amorphous state of solids and liquids was necessary in order to improve our knowledge about their crystalline proper­ ties, growing conditions. and all problems of chemical bonds.
