Abstract

By measuring the magnetocapacitance of high-mobility Si-MOSFET's, we have found that the thermodynamic density of states of a two-dimensional electron gas may become negative in high magnetic fields and at low temperatures. The effect seems to be due to the interactions between electrons.
