Magnetic Crossover in Narrow 2D Electron Systems
Recently, there has been a surge of interest in narrow 2D electron systems in Si inversion layers or GaAs/GaAlAs quantum wells . They show a variety of new phenomena, ranging from two dimensions to one. We are especially interested in the case with a perpendicular strong magnetic field because magnetic crossover in quantization can be expected. Since Landau levels correspond to infinite systems and no exact energy levels are known for finite width, the evaluation of the density of states and conductivity is very difficult.
