Bulashenko, OlegRubí Capaceti, José Miguel2010-01-252010-01-2520020163-1829https://hdl.handle.net/2445/10878Electron transport in a self-consistent potential along a ballistic two-terminal conductor has been investigated. We have derived general formulas which describe the nonlinear current-voltage characteristics, differential conductance, and low-frequency current and voltage noise assuming an arbitrary distribution function and correlation properties of injected electrons. The analytical results have been obtained for a wide range of biases: from equilibrium to high values beyond the linear-response regime. The particular case of a three-dimensional Fermi-Dirac injection has been analyzed. We show that the Coulomb correlations are manifested in the negative excess voltage noise, i.e., the voltage fluctuations under high-field transport conditions can be less than in equilibrium.16 p.application/pdfeng(c) The American Physical Society, 2002Estructura electrònicaSuperfícies (Física)Propietats elèctriquesElectronic structureSurfaces (Physics)Electric propertiesinfo:eu-repo/semantics/article514166info:eu-repo/semantics/openAccess
