摘要: Magnetotransport and drag measurements on a quasi-Corbino two-dimensional electron bilayer at total filling factor of 1 (νT=1) reveal voltage that is equal in magnitude to the drive as soon two layers begin form expected νT=1 exciton condensate. The identity both voltages remains present even elevated temperatures 0.25 K. conductance layer vanishes only limit strong coupling between T→0 K which suggests presence an excitonic circular current.
