Abstract:

Car-Parronello molecular dynamics simulations of twelve nanosized graphene sheets with a dozen to a hundred carbon atoms are performed using a mixed Gaussian and planewave approach within the frame-work of the density-functional theory. Two different origins for the rippled structure of graphene are found: the thermodynamic vibration of atoms and the local lattice defect. We suggest that the lattice defect, which changes the local atomic bonding state, should be responsible for the intrinsic ripples in graphene sheet.

碩士<br>國立成功大學<br>機械工程學系<br>103<br>With the rapid growth of semiconductor process technologies, micro / nano-electromechanical systems is well developed. Nowadays, the conventional semiconductor device can’t meet the requirements because of its weight, bulk and high power consumption. The application of micro / nano electromechanical technology to achieve functional integration, bandwidth, low signal loss and small size requirements is used to solve this problem. Graphene have excellent chemical and machinery stability and it’s suitable for the application of micro / nano components in high spee

Abstract:

The aim of this work is electrochemical exfoliation of pyrolytic graphite for mass production of few-layer graphene nano sheets. It is synthesized by intercalation of graphite sheets in the electrolyte of two different types of concentrations, one molar and two molar concentrations of nitric acid by application of positive bias. The voltage is gradually increased with an increment of 0.5V upto 8V and an interval of 3 minutes. The X-ray diffraction peaks corresponding to graphene sheet ((002) plane) were observed at 2θ positions of 26.35°. The morphology of as-synthesized FLGN

This study includes two parts. In the first part, graphene oxide (GO) was prepared from graphite by modified Hummers’ method, and then was reduced to GNS by NaBH4. In order to improve the dispersion and to prevent the restacking and aggregations of GNS during reduction, [2-(Methacryloyloxy)-ethyl]- trimethyl ammonium chloride (AETAC) was grafted onto

Abstract:

The main objective of the research is to study the potential application of carbon nanotubes and graphene sheets as nano-resonator sensors in the detection of atoms/molecules with vibration and wave propagation analyses. It is also aimed to develop and examine new methods in the design of nano-resonator sensors for differentiating distinct gas atoms and different macromolecules, such as DNA molecules. The hypothesis in the detection techniques is that atoms or molecules attached on the surface of the nano-resonator sensors would induce a recognizable shift in the resonant frequency of or wave

Abstract:

Our vision is as yet unsurpassed by machines because of the sophisticated representations of objects in our brains. This representation is vastly different from a pixel-based representation used in machine storages. It is this sophisticated representation that enables us to perceive two faces as very different, i.e, they are far apart in the “perceptual space”, even though they are close to each other in their pixel-based representations. Neuroscientists have proposed distances between responses of neurons to the images (as measured in macaque monkeys) as a quantification of the “perceptual di

In this thesis work, it has been studied the electronic properties of graphene and graphene like planar nano-sheets. It has been specifically tried to address the problem of band gap engineering in the native as well as functionalized derivatives of graphene and graphene-like planar nanomaterials. In chapter-3, we have solved the tight binding Hamiltonian of graphene. It shows that in a pristine graphene sheet, there is Dirac Cone like merging between the valence band and the conduction band. As a result of which the electrons are highly mobile and shows finite conductivity even at 0 K. Theref

The Angstrom’s method was used to establish a thermal diffusivity measurement instrument. The experimental results showed the room temperature thermal diffusivity of artificial graphite sheet is about (8.24±0.93) x 10^-4 m^2/s, and the values of natural graphite sheets are in the range (2.04±0.26) x 10^-4 to (2.67±0.17) x 10^-4 m^2/s. The experimental results also showed the error within ±10%
