摘要：

This project explores the advantages of Corbino structures to measure thermoelectric transport in the Quantum Hall regime and its metrological applications. Corbino devices were produced from GaAs/AlGaAs heterostructures, whose mobilities ranged from 0.4 to 10 x 10(6) cm(2)/Vs. They have two or several metal contacts to the 2D gas (2DEG) and a central resistive heater. We investigate effects of such contact (ring) disposition and thermal transport by means of its heater.
