SPACE-CHARGE ASSOCIATED WITH FANO-TYPE RESONANCES IN NANOSTRUCTURES

It is shown, by analysis in terms of the eigenvalues of the S matrix, that the Fano type of transmission resonance in nanostructures has the same space-charge property as applies to the simple Lozentzian resona nces. The total space charge in the structure enclosed by the leads, d ue to filling all electron states (of one spin state) over the energy range of a narrow resonance, is equal to just one electron charge.
