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. |
