Novel Electronic Processes in Two-dimensional Systems
Abstract
Earlier, under the previous AFOSR grant, we found direct experimental evidence for the composite fermion model of the Fractional quantum Hall effect. The composite fermion (CF) is the quasiparticle of an electron bound to two magnetic flux quanta by virtue fo the strong electron-electron interaction in the 2D system. The CF's are weakly interacting and experience no external magnetic field at Landau level filling v = 1/2. This report summarizes results from subsequent experiments on these composite particles, carried out under the AF Grant no. F49620-95-1-0071. More specifically: (1) their effective mass, (2) their effective g-factor, and (3) the CF with four flux quanta.
