The model of a superficial current in p-n structures is developed which takes into account displacement of the quasi Fermi level. Is shown, that the semi-conductor lasers on a basis GaAs - AlGaAs can be used for measurement of a parameter of refraction of an environmental liquid, and investigated p-n the structures can be used for the control of partial pressure of ammonia. The size of a critical pressure is found, at which occurs fast degradation of heterostructures5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
