[交流] 求助:请帮忙将一段中文翻译成英文。谢谢!

当电压升到0.5V时,隧穿电子才获得足够能量激发起SPP,并使之分布于氧化层的上下界面。SPP向结内穿透,会对隧穿电子产生阻挡作用,相当于增加了电子的平均有效隧穿距离,且不同时刻SPP波场方向处于交变状态,这将使部分隧穿电子束缚在结的表面,并在结中来回跃迁,这部分电子不能在回路中流动,因而引起回路中的电流突然下降,这就产生了负阻现象。而此后,随着电压的继续上升,隧穿电子继续增加,用于维持SPP激发并束缚于界面的电子数变化不大,因此总体上电流又重新回升。

luckyheizi(金币+50, 翻译EPI+1): 谢谢!请再帮忙把这句也翻译下“当隧穿电子穿过MgO到达Fe原子层,激发其中巡游电子的自旋波,同时也激发了MgO表面的极化激元和Fe表面的等离子震荡,造成能量的分散。” 2011-03-29 11:50:45
Just when the voltage ascends to 0.5 V, tunneling electrons are able to acquire enough energy to stimulate the SPP and to distribute it on the double interfaces of oxide layer. When SPP penetrating through the knot,  it would block the tunneling electrons, which is equivalent to increasing the average effective  tunneling distance of electron, and the SPP wave field directions of different moments are in a alternating state. This will restrict partial tunneling electrons to the knot surface with come-and-go transition. This portion of electrons cannot flow in the loop, which results in a sudden decrease of the electric current in the loop and then negative resistance phenomenonthis appears. Henceforth, with the  climbing voltage, the tunneling electrons continue to increase. As the quantity of electrons for maintaining excitating SPP and bound to the interface change little,the overall current ascend over again.
