Magnetic field impact on electrical properties of ZnSe-GaAs solid solutions
1Institute for Problems of Material Science, 3, Krzhyzhanovsky str., Kyiv, Ukraine
Abstract. The influence of constant magnetic field on thermostimutated current,
photoconductivity, and magnetic susceptibility of ZnSe-GaAs solid solutions were
studied. It was shown that exposition in constant magnetic field results in the
concentration decrease of electrically active deep traps. It leads to the change of
mechanical and magnetic properties of ZnSe-GaAs solid solutions. Proposed was the
healing mechanism based on inhomogeneous distribution of the magnetic susceptibility
in crystal bulk and, therefore, the appearance of randomly distributed external magnetic
fields. Interaction between magnetic moments results in appearance of “driving forces”
promoting defect migration and their annihilation.
Keywords: solid solution, thermostimutated current, photoconductivity, magnetic field.
