An interaction of a moving polaron with a stationary trap is considered in the continuum approximation. Different scenarios — wave function capture and transmission, are possible depending on the polaron velocity. Intermediate cases can also occur. Numerical modelling was carried out for the polaron velocity varying by 3 orders of magnitude. At low polaron velocities, the process is adiabatic and the trap does not capture a charge. At high velocities, the interaction of a polaron with a trap is a highly non-adiabatic and the polaron passes through the trap. At intermediate velocities, the probability of charge capture/transmission oscillates with velocity.

极化子与陷阱的相互作用。连续近似

在连续近似中考虑了移动极化子与固定陷阱的相互作用。不同的场景——波函数捕获和传输,可能取决于极化子速度。中间情况也可能发生。对变化了 3 个数量级的极化子速度进行了数值模拟。在低极化子速度下,该过程是绝热的,陷阱不捕获电荷。在高速下,极化子与陷阱的相互作用是高度非绝热的,极化子穿过陷阱。在中等速度下,电荷捕获/传输的概率随速度波动。
