超导点接触下非平衡声子的重吸收
Reabsorption of nonequilibrium phonons at superconducting point contacts
摘要：
当偏离不等式$d\ll {{l}_{\varepsilon }}$（$d$是接触直径，而${{l}_{\varepsilon }}$是电子的能量弛豫长度）时，在特征声子能量下的$S-c-N$接触的电流-电压特性上产生结构特征，这是因为由于接触附近具有低群速度的非平衡声子的积累而导致$Δ$减小。
英文摘要：
When there is a deviation from the inequality $d\ll {{l}_{\varepsilon }}$ ($d$ is the contact diameter, and ${{l}_{\varepsilon }}$ is the energy relaxation length of the electrons), structural features are produced on the current-voltage characteristics of $S-c-N$ contacts at characteristic phonon energies because of the decrease in $Δ$ due to the accumulation of nonequilibrium phonons with low group velocities near the contact.
