POINT-CONTACT SPECTROSCOPY OF ORGANIC CONDUCTORS [(C2H5)(4)N](0.5)[NI(DMIT)(2)] AND (BEDT-TTF)(2)I-3

Point-contact spectra of organic conductors [(C2H5)(4)N](0.5)[Ni(dmit) (2)] and (BEDT-TTF)(2)I-3 have been measured. The plots of point-conta ct functions of the electron-phonon interaction in these compounds hav e been constructed, and mean and root-mean-square values of frequency have been obtained. The relation between the intensity of the electron -vibrational interaction and conducting properties of the materials un der investigation have been obtained. A correlation is observed betwee n the intensity of these processes and the superconducting transition temperature. The criterion for the synthesis of new organic supercondu ctors is discussed.
