论文摘要
使用一对由纳米级真空间隔隔开的P-和N型半导体，我们引入了一个光电子元件原型“光子P-N结”，作为电子P-N交界处的类似物，被证明是用于理想的近场热量调节器。高调制性能依赖于三种基本光子载体相互作用模式（即表面等离子体层极化子，对称耗尽的内部等离子体极化子和对称累积的表面等离子体极化子）的转换，这是由可调式偏置下孔和电子密度附近的孔和电子密度的变化引起的。该原型不仅为纳米级的非接触式热管理提供了新的想法，而且还为Plasmon Polaritons携带的光电设备的设计设计提供了新的想法。
Using a pair of p- and n-type semiconductors separated by a nanoscale vacuum gap, we introduce an optoelectronics element prototype, "photonic p-n junction", as an analogue of the electronic p-n junction, which is demonstrated to serve as an ideal near-field heat flux modulator. The high modulation performance relies on the switch among three fundamental photon-carrier interaction modes (i.e., surface plasmon polaritons, symmetric depleted internal plasmon polaritons and symmetric accumulated surface plasmon polaritons) caused by the changes in hole and electron densities near the surfaces under a tunable bias. This prototype offers new thoughts not only for contactless thermal management at nanoscale but also for design of optoelectronics devices processing information carried by plasmon polaritons.
