Exploring Corbino Structures for Thermoelectric Transport Under QHE Regime

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 ×10

/V s. 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.
