摘要

我们研究了电子通过纳米级金属收缩时的自发光发射，发现purcell增强发射是由两种不同的机制产生的。在第一种机制中，发射是由电子与介观接触的有效势碰撞引起的，而第二种机制则是电子与收缩壁碰撞引起的。我们发现，与有效势的单次碰撞相比，与壁的多次碰撞可以导致高数量级的光发射概率。

Nanoscale constriction as a source of plasmons for plasmonic nanocircuitries

We investigate spontaneous light emission by electrons passing through a nanoscale metal constriction and find that the Purcell-enhanced emission is engendered by two distinct mechanisms. In the first mechanism emission is caused by electron colliding with the effective potential of the mesoscopic contact while the second mechanism involves collisions of electrons with the walls of the constriction. We find that multiple collisions with the walls can lead to the orders-of-magnitude higher light emission probability in comparison to a single collision with the effective potential.
