Эффект Шубникова — де Гааза Shubnikov–de Haas effect An oscillation in the conductivity of a material that occurs at low temperatures in the presence of very intense magnetic fields , the Shubnikov–de Haas effect (SdH) is a macroscopic manifestation of the inherent quantum mechanical nature of matter. It is often used to determine the effective mass of charge carriers ( electrons and electron holes ), allowing investigators to distinguish among majority and minority carrier populations. https://en.wikipedia.org/wiki/Shubnikov%E2%80%93de_Haas_effect Nano fellow talk -- Probing the surface states in Bi2Se3 using the Shubnikov-de Haas effect Lev Vasilyevich Shubnikov (September 9, 1901 – November 10, 1937) was a Soviet experimental physicist who worked in the Netherlands and USSR . In 1937 he was executed during the Ukrainian Physics and Technology Institute Affair on the basis of falsified charges as part of the Great Purge . https://en.wikipedia.org/wiki/Le...
