RAMIREZ, Asdrúbal A et al. SYSTEMATIZATION OF A MEASURING SYSTEM FOR HALL VOLTAGE AS A FUNCTION OF TEMPERATURE, USING VIRTUAL INSTRUMENTATION. Momento [online]. 2016, n.53, pp.41-53. ISSN 0121-4470.

Abstract This paper presents details of the design and implementation of a system for measuring Hall voltage in dependence of the temperature, developed using the Virtual Instrumentation concept. For that we have used National Instrument hardware and the LabVIEW package as software. The system is controlled by a virtual instrument (VI) which includes facilities to perform PID control of sample temperature in the range of 80 K -700 K, Hall voltage measurement(V_H) using the method of four contacts and real time display of the V_H vs T curve. The system was tested by performing Hall voltage measurements vs T on CuInS₂(CIS)thin films used as the absorber layer in solar cells, for the purpose of obtaining information from its transport properties.

Keywords : Virtual instrumentation; LabVIEW; Hall voltage vs T; electric transport.
