Towards single molecule switches.
The concept of using single molecules as key building blocks for logic gates, diodes and transistors to perform basic functions of digital electronic devices at the molecular scale has been explored over the past decades. However, in addition to mimicking the basic functions of current silicon devices, molecules often possess unique properties that have no parallel in conventional materials and...
متن کاملTransmitting hertzian optical nanoantenna with free-electron feed.
A pair of coupled gold nanorods excited by a beam of free electrons acts as a transmitting Hertzian antenna in the optical part of the spectrum. Significantly enhanced resonant emission is observed from the antenna when the electron beam is injected around the junction between the rods, where the local density of electromagnetic states is elevated.
متن کاملPhotoconductively loaded plasmonic nanoantenna as building block for ultracompact optical switches.
We propose and explore theoretically a new concept of ultrafast optical switches based on nonlinear plasmonic nanoantennas. The antenna nanoswitch operates on the transition from the capacitive to conductive coupling regimes between two closely spaced metal nanorods. By filling the antenna gap with amorphous silicon, progressive antenna-gap loading is achieved due to variations in the free-carr...
متن کاملOptomechanical nanoantenna.
We introduce optomechanical nanoantennae, which show dramatic changes in scattering properties by minuscule changes in geometry. These structures are very compact, with a volume 500 times smaller than free-space optical wavelength volume. This deep subwavelength geometry leads to high speed and low switching power. The bandwidth of the device is about 4.4 GHz, with a switching energy of only 35...
متن کاملSpin-Crossover Materials towards Microwave Radiation Switches
Microwave electromagnetic radiation that ranges from one meter to one millimetre wavelengths is finding numerous applications for wireless communication, navigation and detection, which makes materials able to tune microwave radiation getting widespread interest. Here we offer a new way to tune GHz frequency radiation by using spin-crossover complexes that are known to change their various phys...
