COLÓQUIO - IFUSP: Spins in Semiconductor Nanostructures

In the last decade there has been a strong interest to utilize the spin instead of the charge of carriers in semiconductor devices. Manipulation of the spin allows for faster device operation at a lower energy consumption and offers great opportunities for quantum computing and quantum communication. In this field of semiconductor spintronics there is special interest to control and manipulate the spin of both electrons and holes in zero-dimensional nanostruc-tures. In this presentation I will discuss results, which have recently been obtained at the Eindhoven University of Technology and at the University of Sao Paulo, on analyzing and understanding spins in semiconductor nanostructures. I will present optical spectroscopy performed on large ensembles of nanostruc-tures and on individual nanostructures. The experimental results and theoretical modeling show options on how to modify the g-factor and manipulate the spin of confined carriers. The author has more than 25 years of experience with research on III-V semiconductor nanostructures. He is an internationally leading expert on the application of scanning probe and optical techniques to the study of nanostructures and impurities in semiconductors. His work is presently focused on the spintronic, electronic and optical properties of individual self-assembled nanostructures and single impurities in a semiconductor.
