Study of the effect of an external magnetic field on the photoelectric properties of a copper phthalocyanine film
In the article the results of a study of the influence of a magnetic field on the change in current-voltage char- acteristics and charge carrier mobility in a solid film of copper phthalocyanine (CuPc) are presented. A solid CuPc film on a substrate with a conductive ITO surface (Indium Tin Oxide)...

| description |
In the article the results of a study of the influence of a magnetic field on the change in current-voltage char- acteristics and charge carrier mobility in a solid film of copper phthalocyanine (CuPc) are presented. A solid CuPc film on a substrate with a conductive ITO surface (Indium Tin Oxide) was obtained by thermal evapo- ration in a vacuum. The absorption spectrum of CuPc was measured; as a result, copper phthalocyanine mol- ecules on the substrate surface were found to be in the metastable α-phase. Measurements of current-voltage characteristics (IVC) were carried out using a potentiostat-galvanostat P20X in the linear sweep mode. To study the effect of a magnetic field on the photoelectric characteristics, a sample was placed between the poles of an electromagnet. A xenon lamp with radiation intensity of 50 mW/cm2 was used as a simulator of sunlight. As a result of experiments, it was found that the external magnetic field affects the value of the short-circuit current, at the same time, the charge carrier mobility in a magnetic field does not change. The studied effect of a change in the current-voltage characteristics in a solid CuPc film upon application of an external magnetic field can be used as a high-speed magnetic field sensor.
