摘要：

We study the feasibility of ballistic electron spectroscopy using a quantum dot (QD) as an energy selective detector. Our device consists of two QDs, one used to prepare ballistic electrons with a well defined excess energy and the other used to demonstrate their detection. We use magnetic field dependence to demonstrate the ballistic nature of the detector signal and show the energy selectivity for varying excess energy of the ballistic electron beam.
