LABORATORY "THEORY OF NANOSTRUCTURES"

GENERAL REMARKS

With the advent of modern thin-film and nanofabrication techniques, the interest in small magnetic structures has recently rapidly increased. The reason for this is that, on the one hand small structures of this type e.g., in a form of quantum dots, quantum nanowires or quasi 2-dimensional systems show quite fascinating properties like resonant-tunneling, Coulomb blockade, Kondo effect and conductance quantization or - in the presence of magnetic field - the Aharanov-Bohm effect and the quantum Hall effect. On the other hand, in case of structures containing magnetic ingredients there appears a new possibility of controlling electrical current by switching on and off magnetic field. This way, the electron spin has entered the modern electronics, and starts playing a crucial role. This is in contrast to traditional electronic devices, like silicon transistors, in which only carrier charge is of importance and no use is made of its spin.

SCIENTIFIC ACTIVITIES

Research carried out in our Laboratory "Theory of Nanostructures" concern electrical and magnetic properties of systems with reduced geometry. This class of materials consists not only of traditional, studied for many years, thin films and multilayers, but includes also new man-made artificial systems (e.g., nanowires, nanoparticles, quantum dots and so on). In such systems the spin coherence length is often longer than the size in the current flow direction, so one can control their transport properties with magnetic field. This opens new possibilities for application of nanostructure materials, e.g., as magnetic field sensors and random access memories.

We study the following problems :
