Singularity in the density of states of quasionedimensional disordered systems
Abstract
We have calculated the correction to the densityofstates in twodimensional weakly disordered systems. It is shown that the electronelectron interaction gives rise to a singularity in the densityofstates at the Fermi level, the form of which is very sensitive to the width of the sample. The transition from a twodimensional behaviour to the quasionedimensional regime is discussed. The effects should be observable by electron tunnelling measurements.
