【摘要】 计算了在不同电子-晶格耦合强度λ下,一维电子-晶格体系中孤子激活能ε₁（λ）及电子激发到禁带中央分立能级所需能量△（λ）。得到孤子激活能随λ增大而增大;但对不同λ,孤子激活能总是小于产生一个电子或空穴所需能量。更多还原

【Abstract】 The excitation energy of soliton ε1 and its dependence upon electronlattice coupling: strength λ have been calculated in strongly coupled one dimensional electron-lattice systems. Our results show: The excitation energy of soliton ε1(λ) augments as λ increases. Whereas, ε1, will be always less than the energy needed to excite an electron or a hole in this system.更多还原
