Control of lectronic onduction at an xide eterointerface using olar dsorbates

چکیده
We study the effect of the surface adsorption of a variety of common laboratory solvents on the conductivity at the interface between LaAlO3 and SrTiO3. This interface possesses a range of intriguing physics, notably a proposed connection between the surface state of the LaAlO3 and the conductivity buried in the SrTiO3. We show that the application of chemicals such as acetone, ethanol, and water can induce a large change (factor of three) in the conductivity. This phenomenon is observed only for polar solvents. These data provide experimental evidence for a general polarization-facilitated electronic transfer mechanism. SLAC-PUB-14500

متن کاملObservation of high-speed microscale superlubricity in graphite.
A sheared microscopic graphite mesa retracts spontaneously to minimize interfacial energy. Using an optical knife-edge technique, we report first measurements of the speeds of such self-retracting motion (SRM) from the mm/s range at room temperature to 25 m/s at 235°C [corrected]. This remarkably high speed is comparable with the upper theoretical limit found for sliding interfaces exhibiting s...
متن کاملXIDE: Expanding End-user Web Development
Most Web end-user development tools assume that users create Web applications entirely visually. However, such tools have a limited functionality and support inadequately the transition from visual editing to source code editing. In this paper, we introduce a tool, XIDE, that supports end users in creation of database-driven Web applications. The proposed tool is based on three main approaches:...
