Expertise

Bart van Wees is an expert in quantum electronic charge transport and spintronics in metal, semiconductor, insulator and graphene based systems. He is one of the pioneers of quantum ballistic transport in mesoscopic and nanostructures. Over 25 years ago he and his colleagues demonstrated the quantization of the conductance in units of 2e2/h in ballistic quantum point contacts. The expertise of his group includes nanodevice fabrication, dedicated charge and spin transport measurements, facilities for large magnetic field and low temperature measurements, modellling of spin and transport.
