Abstract: 
For complex investigations of voltage-current characteristics of semiconductor and super conductor film heterostructures in a wide temperature interval at with influence of current injection, magnetic-field, and also optical radiation, was created computerized informational measuring cryocomplex (IMC). IMC allows to realize the precise stabilizing of temperature of semples in a range from 1,6 to 373 K, to influence the magnetic field by induction to 2 Т, to conduct measuring volt-ampere characteristic with possibility of management by a «pumping current», that is especially important at researching of transistor structures. Personal computer software allows to automatize the concerted work of the modules of complex, and also processing, saving and presenting of these measuring data. The work is carried out within the framework of the Program of scientific instrument making of NАS of Ukraine, grant P-9/40.
Keywords: film heterostructures, informational measuring complex, tunnel effect in superconductors, volt-ampere characteristics measuring
