Optical studies of spin phenomena using a two-color Kerr rotation technique with micron spatial resolution and ultra-high polarization sensitivity

We propose a systematic research program covering the spintronics aspects of spin flow, spin relaxation and spin separation in semiconductor nanostructures. Our proposal is based on all-optical techniques that are sensitive to as few as 104 electron spins with micron spatial (lateral) resolution. The research plan consists of several sub-projects that are closely related to each other and individually address important problems (either arising from earlier studies or following from theoretical predictions that have not been examined experimentally yet). This will allow us to draw a coherent physical picture of the considered phenomena and optimize or suggest structure parameters for future investigations and applications.
