摘      要：Reducing the capacitive opening between subwavelength metallic objects down to atomic scales or bridging the gap by a conductive path reveals new plasmonic spectral features,known as charge transfer plasmon(CTP).We review the origin,properties,and trending applications of this modes and show how they can be well-understood by classical electrodynamics and quantum mechanics *** important is the excitation mechanisms and practical approaches of such a unique resonance in tailoring high-response and efficient extreme-subwavelength hybrid nanophotonic *** the quantum tunnelinginduced CTP mode possesses the ability to turn on and off the charge transition by varying the intensity of an external light source,the excited CTP in conductively bridged plasmonic systems suffers from the lack of *** address this,the integration of bulk plasmonic nanostructures with optothermally and optoelectronically controllable components has been introduced as promising techniques for developing multifunctional and high-performance CTP-resonant *** tunable plasmonic devices such as metamodulators and metafilters are thus in prospect.
