Thermoelectricity: From History to Modernity Through the CASS Activity

October 2020 has become remarkable for commemorating the 140th birthday of the outstanding academician A.F. Ioffe - "the father of Soviet physics." A.F. Ioffe supervised the first research projects on semiconductor physics, in particular, thermoelectricity. In this article, we introduce the great scientific contributions of A.F. Ioffe and several research projects of the members of the IEEE CAS Chapter, St. Petersburg, based on the results of Ioffe's scientific group.
