 The Rimberg Group performs electrical transport measurements to study the properties of nanostructures including quantum dots and tunnel junctions using radio-frequency single electron transistors as a probe. We have two goals: first to understand the fundamental physics of such small structures; and second to use them to produce devices with novel transport properties and potential applications. We use electron beam lithography to fabricate our devices, and then use custom electronics and specialized low-noise and microwave measurement techniques to make our precision measurements. We are particularly interested in the dynamics of individual electrons, and in real-time observation of quantum phenomena.
