Abstract : IN THE BROAD FIELD OF CRYSTAL PHYSICS, THREE MAIN PROBLEMS ARE UNDER STUDY, (1) preparation and purification of starting materials for crystal growth, (2) study of crystal growth and practical crystal growing, (3) investigation of intrinsic and structure-sensitive properties of single crystals. Processes of crystal growth from solution and melt and by flame fusion were studied. A variety of organic, inorganic, and metal crystals were grown for the study of their propertiesAND SPECIAL EFFECTS. Imperfections of crystals were studied by means of high-precision latticeconstant determination, weighing density, thermal etching, ionic conductivity, and optical absorption. A great part of the work was devoted to a study of electron and hole traps in pure and doped crystals by means of color centers. (Author)
