Abstract

Electrical detection of surface plasmons polaritons (SPPs) is essential for realization of integrated fast nanoscale plasmonic circuits. We demonstrate electrical detection of SPPs by measuring their remote gating effect on 1G(0) metal quantum point contacts (MQPC) made of gold. Gating is argued to take place by a photoassisted transport mechanism with nonmonotonic behavior of its magnitude as a function of distance between the MQPCs and the position of SPPs creation.

摘要

表面等离激元极化激元（SPPs）的电检测对于实现集成的快速纳米级等离子体电路至关重要。我们通过测量它们对由金制成的 1G(0)金属量子点接触（MQPC）的远程门控效应来证明 SPPs 的电检测。门控被认为通过光辅助输运机制发生，其大小的非单调行为作为 MQPC 之间的距离和 SPPs 产生位置的函数。
