Promoted electron transport and sustained phonon transport by DNA down to 10K
This work reports on a pioneering study of the electron transport in nanometer-thick Ir film supported by a DNA fiber, and the phonon transport sustained by the DNA itself. By evaluating the electrical resistivity (re)~temperature relation based on the Block-Grüneisen theory, we find the Ir film has weak phonon softening indicated by 7e15% Debye temperature reduction. The Ir film's intrinsic re...
متن کاملTemperature Dependence of Electrical and Thermal Conduction in Single Silver Nanowire
In this work, the thermal and electrical transport in an individual silver nanowire is characterized down to 35 K for in-depth understanding of the strong structural defect induced electron scattering. The results indicate that, at room temperature, the electrical resistivity increases by around 4 folds from that of bulk silver. The Debye temperature (151 K) of the silver nanowire is found 36% ...
متن کاملThermal transport in DNA
Thermal transport in DNA is systematically studied to facilitate the development of DNA-based nanoelectronics in thermal management aspect. Synthesis of crystalline DNAcomposited microfiber and microfilm, DNA nanofiber and DNA nanofiber array are developed in sequence to enable the thermal transport study in them. Thermo-physical properties, including thermal conductivity, thermal diffusivity, ...
متن کاملThermal conductivity of graphene with defects induced by electron beam irradiation.
We investigate the thermal conductivity of suspended graphene as a function of the density of defects, ND, introduced in a controllable way. High-quality graphene layers are synthesized using chemical vapor deposition, transferred onto a transmission electron microscopy grid, and suspended over ∼7.5 μm size square holes. Defects are induced by irradiation of graphene with the low-energy electro...
متن کاملPolyester/SiO2 Nanocomposites: Gas Permeation, Mechanical, Thermal and Morphological Study of Membranes
Using of nanocomposite membranes composed of polymer and inorganic nanoparticles is a novel method to enhance gas separation performance. In this study, membranes were fabricated from polyester (PE) containing silica (SiO2) nanoparticles and gas permeation properties of the resulting membranes were investigated. Morphology of the membranes, SiO2 distribution a...
