Abstract

Application of LaAlO₃/SrTiO₃ interfacial two-dimensional electron gas (2DEG) as a polar molecule sensor is demonstrated. The sensing mechanism is due to the formation of a metal-semiconductor Schottky junction when the center of LaAlO₃surface is covered with polar molecules such as water. These results also evidence the existence of a polarization field inside the LaAlO₃/SrTiO₃layer. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
