Abstract:

Given the current level of interest in nanotechnology, spintronics, quantum information etc... it is interesting to ask what benefits one would expect from connecting a nanostructure, in this case a quantum dot, to spin polarized leads. In this talk I will try to answer this using results from few electron lateral quantum dot devices. I will show how this leads to a form of spin blockade spectroscopy which enables the direct observation of spin transitions (both expected and unexpected) in single and coupled quantum dot systems. Other benefits such as providing a readout function for spin qubits will also be briefly described.
