In this study, the authors investigated the effects of a single layer graphene as a coating layer on top of metal thin films such as silver, gold, aluminum and copper using finite-difference time domain method. To enhance the resolution of surface plasmon resonance (SPR) sensor, it is necessary to increase the SPR reflectivity and decrease the full-width-half maximum (FWHM) of the SPR curve so that...
Electrofusion can be performed by forming cell-cell contact, while simultaneously applying pulsed high voltage electric fields to induce the fusion. Mechanisms of forming cell-cell contact has been demonstrated by various methods including biochemical, chemical, mechanical and electrical methods. Dielectrophoresis has been utilized in electrical based cell-cell contact formation. In this work, we...
In this paper we report successful experimental demonstration of consistency in controlling the resonance quality factor (Q-factor) value in the range from 1000 to 80,000, together with good free spectral range (FSR) control in the range from 30 nm to 62 nm — for an extended cavity. We have also demonstrated good repeatability of high Q-factor values for 1D photonic crystal (PhC)/Photonic wire (PhW)...
Atomic force microscopy nanolithography (AFM) is a strong fabrication method for micro and nano structure due to its high spatial resolution and positioning abilities. Mixing AFM nanolithography with advantage of silicon-on-insulator (SOI) technology provides the opportunity to achieve more reliable Si nanostructures. In this letter, we try to investigate the reproducibility of AFM base nanolithography...
The variation of electrical characteristics with nano size air gap variation between gates and channel of a pinch off lateral gate transistor were investigated using 3D Technology Computer Aided Design. It is found that smaller nanosize gaps which can be formed by approaching the lateral gates to the channel can improve the switching performance of the device significantly. Devices with different...
Remote energy efficiency for wireless micro sensor devices in multimedia, signal processing and communication technologies is of paramount interest not only for ensuring continuous network operation despite primary battery limitations, but also for reducing carbon footprint in communication systems. Increasing demands of energy supply for micro devices, in particular, with the advance of complex multimedia...
One of the major pitfalls of multi liquid phase optofluidics is that it is difficult to adjust and tune the physical properties of the liquids that flow through these systems, on the fly. In this work, we demonstrate a viable solution through the use of a single mode polymeric waveguide integrated with dielectrophoretically controlled mesoparticles. We show a promising way of achieving fluidic property...
Side gate p-type Junctionless Silicon transistor is fabricated by AFM nanolithography on low-doped (105 cm−3) SOI wafer. In this work, the simulation characteristic of the device using TCAD Sentaurus in on state will be studied. The results show that the device is the pinch off transistor, works in on state for zero gate voltage in depletion mode. Negative gate voltage drives the device into on state,...
Double gate junctionless (DGJLT) transistor, as a pinch off device, was previously fabricated. In this letter, the impact of channel width variation on behaviour of the device is studied by means of 3D-TCAD simulation tool. In this matter, the transfer characteristics, energy band diagram (valence/conduction band) and normal electric field along the nanowire between the source and the drain are studied...
