Abstract: | Two 7,7,8,8-tetracyanoquinodimethane (TCNQ) complexes with cystein and guanine have been investigated. EPR spin signals of these charge transfer complexes were recorded and the electron spin lattice relaxation time (T1) temperature dependence was investigated. The electron scattering time, calculated from T1, agreed reasonably well with that from the current carrier effective mass (as determined through the Hall mobility measurements). |
