Abstract

The work presents the result of modernization of the equipment and methods of performing the work of the general physics laboratory practice. Modernization was carried out with the aim of giving the work of the workshop elements of research activity. Using the example of thematically related laboratory works from the section "Electricity and Magnetism", it is shown that the combination of several laboratory works into one study of the electrophysical properties of semiconductor materials provides an opportunity to gain deeper knowledge about the object of research and contributes to the development of research activity skills of physics students. The work investigated semiconductor diodes manufactured using different technologies: Schottky diode MBR2045, high-voltage p – i – n diode STTH6012 and diode with p – n junction D92 – 02. The study consisted of studying volt-ampere, volt-farad characteristics and temperature dependences of the reverse current of each of the specified products. The measurement results were processed using modern theoretical models of semiconductors. The equipment and skills acquired by students during the performance of such complex laboratory work can be used in research work if there are appropriate tasks.
