Abstract

The compressibility of composite fermion metallic state in two-dimensional electron system (2DES) was measured. A comparative study of the derivative of the chemical potential with respect to the carrier density at zero magnetic field was performed. The derivatives were calculated from the bottom of the ground subband. This derivative was inversely proportional to the 2DES compressibility. The contribution of electron-electron interaction was found to be identical for metallic states of electrons at zero magnetic field and of composite fermions at Landau level filling 1/2.
