Laurens W. Molenkamp
Laurens W. Molenkamp obtained his Ph.D. from the University of Groningen in 1985 working on ultrafast coherent spectroscopy. He then joined Philips Research Laboratories in Eindhoven, working on semiconductor lasers and subsequently on mesoscopic transport in semiconductors. In 1994, he was appointed as Professor of Experimental Physics (C3) at the RWTH in Aachen, Germany, in 1994. He moved to Würzburg University in April 1999 as the Chair of Experimental Physics (EP3), where he continues research in quantum transport and semiconductor spintronics.
Convincing a magnetic semiconductor to work at room temperature
In the design of spintronic devices, magnetic semiconductors have the potential to be an “all in one material,” but they are usually ferromagnetic only at low temperatures. However, by growing an iron layer on top of a magnetic semiconductor it is possible to induce room-temperature ferromagnetism in a thin layer near the interface. Read More »
