According to Peierls phase transition theory based on the electron-phonon interaction, the Peierls phase transition temperature of a one-dimensional organic conductor tetrathiafulvalene-tetracyanoquinodimethane is computed using the deformation potential model with the data calculated by a semi-empirical crystal orbital method. The mechanism of the metal-insulator phase transition in this conductor is also discussed.
