Tunable thermal switching via DNA-based nano-devices

Tunable thermal switching via DNA-based nano-devices.

DNA has a well-defined structural transition--the denaturation of its double-stranded form into two single strands--that strongly affects its thermal transport properties. We show that, according to a widely implemented model for DNA denaturation, one can engineer DNA 'heattronic' devices that have a rapidly increasing thermal conductance over a narrow temperature range across the denaturation ...

Tunable graphene-based plasmonic waveguides: nano modulators and nano attenuators

O R IG IN A L P A P ER Abstract A modulation principle and method, the gatevoltage-controlled mode-guiding switching/mode-cutoff mechanism, is proposed and numerically investigated to achieve the modulation/attenuation function. The propagating attenuation of the graphene 2D waveguide as a function of the Fermi level of the cladding is analyzed. Different modes with low or high attenuations in ...

Investigation of thermal tunable nano metallic photonic crystal filter with mirror symmetry

Using the transfer matrix method, the effect of temperature on thetransmission spectra of thermal tunable nano metallic photonic crystal filter has beeninvestigated. Three different materials H (high refractive index material), L (lowrefractive index material) and M as a metallic layer, have been used to make thisstructure. M layer is considered to be Silver. The complex refractive index of Sil...
