The course starts with a broad overview of the fascinating novel approaches for nanoscale electronics that are emerging. Then, we focus on three main themes within nanoelectronics, namely (i) spin electronics or, in short, spintronics. (ii) quantum electronics, and (iii) organic and molecular electronics.
In the spintronics section, we review the basis magnetic properties of atoms and magnetic materials, discuss the magnetic behavior of various nanostructures (ultrathin films and multilayers, nanowires, nanoparticles), and give a basic introduction to electronic transport in magnetic systems. Concerning the latter, we discuss spin polarization, magnetoresistance, magnetic tunnel junctions, spin-transfer torque, and spin-dependent transport in semiconductors, illustrated with apllications such as sensors, MRAM and magnetic FETs.
Regarding quantum electronics, we start out with electron interference effects in nanostructures, 2-dimensional electron gases in semiconductor heterostructures, and quantized conduction. We then discuss single-electron transistors based on (single- and double) quantum dots, where Coulomb blockade effects and discrete electronic level structure play an essential role.
Organic, molecular semiconductors are introduced with a review of their electronic structure, where we emphasize the electron-lattice(phonon) coupling and geometrical relaxation effects. We then address electronic transport and recombination effects, and finish with single molecule electronics, and organic spintronics using hybrid structures comprising organic semiconductors and ferromagnetic materials.
