Pictures of the Fractional Quantized Hall Effecton between integral and fractional quantized Hall effect.it is concluded that the fractional quantized Hall effect is of many-particle origin. A simplified approach to the presently prevailing theoretical model of the electronic groundstate and its quasi- particle excitations is presented, together

Photoluminescence in Semiconductor Quantum Wellsluminescence when this excitation is obtained by light absorption. As described in the first part of this lecture by P. Voisin, an absorption spectrum provides informations essentially on the densities of states in valence and conduction bands and looks like a continuous spectrum above the 2D system

Optical Properties of 2D Systems in the Far Infraredhis lecture I will discuss the fundamental optical properties of a 2D electron layer embedded between a semiconductor and isolator. Fundamental excitations such as cyclotron resonance [1–7], 2D plasmons [8–10] excited via grating couplers and the blackbody emission [11,12] from hot 2D electrons will
