RESEARCH ON IMPROVED II-VI CRYSTALS.
Abstract
'Sulfur compensation' of excess donors in CdS to obtain uniform, high-resistivity crystals without appreciable overcompensation may require a composite heat-treating procedure, since an acceptable short heat-treating time with the required high S pressure is not compatible with uniform crystal properties. The electroneutrality equation is put into a general, solvable form by evaluation of the various equilibrium constants defining the formation and relationship of all of the probable native and foreign centers occurring in II-VI compounds. By use of a computer, the temperature dependence of the concentration for these various centers are readily calculated and the stability field of the solid is then defined. Initial application of this procedure is to ZnTe. (Author)
