摘要
The statistical weight W as a function of energy E for quasielectrons with mass m* subject to a fixed magnetic field B is W/A = (m*/pi h(2))E + (eB/pi h(2))Sigma(infinity)(v-1)(-1)(v) v(-1) sin(pi vE/hwc), where A is the sample area, and w(c) congruent to eB/m* the cyclotron frequency. Significantly, there is no Landau term proportional to B-2 in 2D. This leads to the conclusion that the 2D electron system is always paramagnetic, but shows a magnetic oscillation.
