【Abstract】 In this article, a simple model potential is introduced to simulate quasi-one-dimensional structure of organic material. The Non-Damping Acoustic Plasmons (NDAP) is obtained by the Random Phase Approximation and the theory of linear response. Thus the NDAP mechanism of superconductivity in quasi-1-d organic material is proposed. Its applications in (TMTSF)2PF6-a quasi-1-d organic superconductor, and TMTSF-DMTCNQ-a quasi-1-d organic conductor are discussed and calculated. The results show that it is entirely possible to get quasi-1-d organic superconductors with high Tc. Finally, the condition favourable to the appearance of superconductivity with higher Tc is discussed.更多还原
