Rfbr Grant Internship: Assistant Researcher
Ioffe Institute
St Petersburg, St Petersburg City, Russia
As part of support for the mobility of young researchers, I was awarded a grant from the Russian Foundation for Basic Research (RFBR). Under the guidance of Alexander Burkov, the head of the Laboratory of Thermoelement Physics at the Ioffe Institute, I conducted measurements of the electrical transport properties of rare-earth substituted BiCuSeO oxyselenides. This involved:- Maintaining, designing, and upgrading a laboratory-made setup for measuring electrical transport properties in the temperature range from 100 to 1200 K.- Conducting electrical resistivity and Seebeck coefficient measurements using the standard 4-probe and differential methods, respectively, under a helium atmosphere with a homemade system.- Measuring the temperature-dependent Hall constant through a high-resolution double-frequency AC technique, utilizing another custom-made apparatus.- Analyzing the data within the framework of the effective mass theory.------Supervisor: Alexander Burkov - Laboratory of Thermoelement Physics, Ioffe Institute (Saint-Petersburg, Russia)Mentor: Sergey Novikov - Laboratory of Thermoelement Physics, Ioffe Institute (Saint-Petersburg, Russia)
