| 摘 要： | 采用线性组合算符法和变分法研究了电场对抛物量子线中强耦合极化子性质的影响，在考虑电子与LO声子相互作用和加电场的情况下，计算了抛物量子线中强耦合极化子的基态能量．数值计算结果表明：抛物量子线中强耦合极化子的基态能量Eo随约束强度ω0的增强而增大，而随电场强度F和量子线长Z的增大而单调减小．

| Abstract: | The influence of electric field on the properties of strong - coupling polaron in parabolic quantum wires are studied by using linear combination operator and variational methods. The ground state energy of strong - coupling polaron in parabolic quantum wires is calculated for the case where the electron interacted with bulk LO phonon and added electric field. Numerical calculation illustrated that the ground state energy increases with the increasing confinement strength, and decreases with increasing of electric field strength and wire length. |
