Phonon Conductance of Potassium- and Sodium-Doped Transpolyacetylene Chain
Figure 1
(a) A transpolyacetylene chain structure, showing the unit cell bounded by a box defined by the dotted lines with two inequivalent Carbone atoms A and B in the unit cell. (b) A schematic representation of doped transpolyacetylene chain. The doped unit cell may contain different masses and force constants. The elastic constants in the boundary may also be different from the rest of the undoped transpolyacetylene chain. The doped unit cell, the incident waves (IW), the reflected waves (RW) and the transmitted waves (TW) are shown. The two perfect wave guides (LW) and (RW) and the two matching domains (LMD) and (RMD) are also indicated.
