Critical behaviour of thermopower and conductivity at the metal-insulator transition in high-mobility Si-MOSFETs

This paper reports thermopower and conductivity measurements through the metal-insulator transition for 2-dimensional electron gases in high mobility Si-MOSFETs. At low temperatures both thermopower and conductivity show critical behaviour as a function of electron density. When approaching the critical density from the metallic side the diffusion thermopower appears to diverge and the conducti...

Metal-insulator transition in ultrathin LaNiO3 films.

Transport in ultrathin films of LaNiO(3) evolves from a metallic to a strongly localized character as the film's thickness is reduced and the sheet resistance reaches a value close to h/e(2), the quantum of resistance in two dimensions. In the intermediate regime, quantum corrections to the Drude low-temperature conductivity are observed; they are accurately described by weak localization theor...
