Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Selenium and Tellurium contains the proceedings of the International Symposium on the Physics of Selenium and Tellurium held in Montreal, Canada, on October 12-13, 1967 and sponsored by the Selenium-Tellurium Development Association, Inc. The papers explore the physics of selenium and tellurium, with emphasis on band structure, crystal growth and characterization, optical properties, and electrical properties. This book consists of 33 chapters and opens with a review of progress in the physics of selenium and tellurium, particularly with respect to the mechanical and thermal properties of trigonal selenium and tellurium and their lattice dynamics. The following chapters focus on calculations of the band structure of selenium and tellurium; magnetoabsorption in tellurium; trapping levels in hexagonal selenium; and coordination and thermal motion in crystalline selenium and tellurium. Infrared-active lattice vibrations in amorphous selenium and the contribution of lattice vibrations to the optical constants of tellurium are also discussed. This monograph will be a useful resource for physicists.

Available in PDF, EPUB and Kindle. Book excerpt: Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.
