Abstract : Three years ago, we developed "Single-Electron Capacitance Spectroscopy" (SECS). This is a means for measuring the quantum energy levels of nanoscale objects such as quantum dots, single impurity atoms, and localized electronic states in a semiconductor. The resolution of the method is limited only by the sample temperature, and objects containing as few as one electron may be probed. We intend to develop this type of single electron spectroscopy into a general tool for studying nanostructured materials. jg p.2
