ELECTRON TRAPS IN LONG-CHAIN ALKANESMarek Pietrow, Jan Wawryszczuk Institute of Physics, Maria Curie-Skłodowska University, 1 M. Curie-Skłodowskiej Sq., 20-031 Lublin, Poland Positron lifetime spectra in long-chain alkanes were measured at various wavelengths of light illuminating the samples as a function of temperature, storage time. It was found that in n-alkanes with carbon chain longer than 30 atoms two kinds of electron traps exist; the depth of shallower of them is less than 0.52 eV. They are discharged already at a temperature of 120 K. Close X |
