Abstract

Single electron devices (SEDs) are electronic devices that can isolate electrons along a conducting path. SEDs have potential applications in the field of metrology (the science of measurement) and quantum computation. These different applications require the device to be tuned to different operating regimes. Here we investigate a SED with a simple device design and tune it to the single quantum dot regime. To achieve this, we measure current through the device as a function of applied gate voltages. By mapping the current as a function of applied voltages, we measure charge stability diagrams associated with the behavior of a single quantum dot thereby verifying our ability to tune the device to this regime. However, our results reveal a large amount of disorder in our device.
