Electrons on the double helix: optical experiments on native DNA

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/18534Optical experiments on calf thymus DNA films subjected to different buffer environments are reported. The optical conductivity is that of a disordered or lightly doped semiconductor with a well-defined band-gap for charge excitations and low frequency transport determined by a small number of strongly localized electron states.5 pages, 3 figures submitted to PRLDisordered Systems and Neural NetworksSoft Condensed MatterQuantitative BiologyElectrons on the double helix: optical experiments on native DNAtext
