Evidence of Novel Quasiparticles in a Strongly Interacting Two-Dimensional Electron System: Giant Thermopower and Metallic Behaviour

Vijay Narayan, M. Pepper, J. Griffths +5

We report thermopower ($S$) and electrical resistivity (${\rho }_{2DES}$) measurements in low-density (10${}^{14}$ m${}^{-2}$), mesoscopic two-dimensional electron systems (2DESs) in GaAs/Al…
