摘要:

AbstractThermodynamics of A3B5semiconductor crystal, containing impurity and native point defects is considered. The main limit of the present analysis is the absence of a significant interaction between point defects at thermal equilibrium. It is shown that the difference of the chemical potentials of A3and B5components may serve as a structural sensitive thermodynamic function of a crystal. The optimization of the crystal perfection may be obtained when this function becomes zero. In the case of undoped A3B5crystal such a situation corresponds to the ideal lattice perfection. In the case of doped crystal the effects of native point defects and their interaction with the impurity on the electronic properties of the crystal have to be reduced.The developed thermodynamic approach has been applied to the quantitative analysis of the available experimental data (GaAs, GaP, GaAs:Si and GaP:In). The results of the calculation are in reasonable agreement with the experiment.

摘要:

AbstractSingle crystal platelets of cadmium iodide have been grown from alcohols: n‐propyl, isobutyl and isoamyl and from their aqueous solutions. The structures of 880 crystals has been identified and the effect of solvent on the polytype structure of CdI2has been discussed regarding: the stability of the basic structures 2H and 4H, the structure of complex polytypes, the effect of the solvent on the structure of faults, the period of polytypes. Some relations indicating the role of the solvent in the formation of polytype structure of CdI2have been foun

摘要:

AbstractAssuming a film‐edge induced stress distribution in an isotropic crystal, the shear stresses in the glide systems of a diamond‐type semiconductor substrate are calculated. Quantitative information on magnitude and position of the respective shear stress maxima is obtained in dependence on crystal orientation and technologically relevant film configurati
