Introduction Various forms of carbon nanomaterials such as fullerenes, carbon nanotubes, Nano diamonds and other carbon nanomaterial’s have been rapidly developed not only for their unusual electrical and mechanical properties, but also for their potential use in Nano fluidic device [1-9]. Since 2003 Kawase et al. [10] reported the synthesis of the first Nano rings, a family of similar material...

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

Temperature measurement with nano-Kelvin resolution is demonstrated at room temperature, based on the thermal dependence of an optical crystal anisotropy in a high quality whispering gallery mode resonator. As the resonator's TE and TM modes frequencies have different temperature coefficients, their differential shift provides a sensitive measurement of the temperature variation, which is used ...

We report on the fabrication and operation of a multi-element vibrational structure consisting of two graphene mechanical resonators coupled by a nanotube beam. The whole structure is suspended. Each graphene resonator is clamped by two metal electrodes. The structure is fabricated using a combination of electron-beam lithography and atomic-force microscopy nano-manipulation. This layout allows...

High sensitivity magnetoelectric sensors with their electromechanical resonance frequencies < 200 kHz have been recently demonstrated using magnetostrictive/piezoelectric magnetoelectric heterostructures. In this work, we demonstrate a novel magnetoelectric nano-electromechanical systems (NEMS) resonator with an electromechanical resonance frequency of 215 MHz based on an AlN/(FeGaB/Al2O3) × 10...

Electro-optic modulators lie at the heart of complex integration and high-density electro-optic systems. One representative is thin-film lithium niobate-based microring modulator which has demonstrated advantages compact footprint, low optical loss, high modulation efficiency. However, linewidth extinction ratio ring are fundamentally limited by losses coupling, respectively. To this end, a nov...

Graphene has received significant attention due to its excellent mechanical properties, which has resulted in the emergence of graphene-based nano-electro-mechanical system such as nanoresonators. The nonlinear vibration of a graphene resonator and its application to mass sensing (based on nonlinear oscillation) have been poorly studied, although a graphene resonator is able to easily reach the...
