Abstract
We present real‐time detection of single electrons in an InAs nanowire double quantum dot. Two self‐aligned quantum point contacts in an underlying two‐dimensional electron gas material serve as highly sensitive charge detectors for the double quantum dot. We examine the excitated states of the double quantum dot by finite bias spectroscopy. The excited states are characterized by measuring the tunneling‐in and tunneling‐out rates of the quantum dots.
