SOLITONS WITH A LOCALIZED ELECTRONIC-STATE IN QUASI-ONE-DIMENSIONAL CONDUCTORS WITH A CHARGE-DENSITY-WAVE

It is shown that self-trapped soliton states, in which the position of the electronic level in the Peierls gap 2 Delta is shifted from the c enter of the gap by an amount of the order of Delta, can exist in quas i-one-dimensional conductors possessing a charge-density wave. The ene rgy of the level is determined by the local position of the chemical p otential and depends on the parameters of the crystal and the temperat ure. (C) 1996 American Institute of Physics.
