Abstract:
Films and coatings of carbonaceous nanostructures are employed in nanoelectronics, biotechnology and other fields. The aim of the research was to synthesize multi-walled carbon nanotubes and graphite oxide and fabricate coatings thereof. Consequently, multi-walled carbon nanotubes and their coatings were synthesized by the catalytic chemical vapour deposition method. As-grown carbon nanotubes inevitably contain remains of metal catalyst particles. A method developed in the laboratory using CCl4 was successfully applied to remove the residual catalyst from the batch of synthesized carbon nanotu

Carbon based and inorganic nanostructures have been produced and characterized by spectroscopic (XPS, Raman) and microscopic (SEM, TEM, AFM) techniques. The inorganic species obtained (MoSI) can be used to produce conductive nanonetworks with metal nanoparticles. A reaction pathway leading to the MoS2 production by laser ablation in liquid has been proposed. Alternative ways to produce carbon based nanostructures (nanotubes, nanowires and graphene) have been studied. Carbon nanotubes have been produced by arc discharge in liquid nitrogen and the influence of the arc parameters on the ID/IG val

The technique of DNA origami utilizes the specific and limited bonding properties of DNA to fold single stranded DNA sequences of various lengths to form a predesigned structure. One longer sequence is used as a scaffold and numerous shorter sequences called staples, which are all complementary to the scaffold sequence, are used to fold the scaffold into intricate shapes. The most commonly used scaffold is derived by extracting the genome of the M13 phage and the staples are usually chemically synthesized oligonucleotides. Longer single stranded sequences are difficult to synthesize with high

After annealing the deposited structures, the carbon templates were either left in place to give hybrid structures or oxidized to leave pure inorganic nanoparticles.

碩士<br>大同大學<br>材料工程學系(所)<br>97<br>Organic light-emitting devices (OLED) has become an oncoming flat panel industry in recent years, and the key issue is to promote the luminous efficiency of the devices. In fact, only a small fraction (20%) of the total ptotons generated inside the OLED are generally useable, how to extract the photons from the OLED is an important topic nowadays. Two-dimensional photonic crystal (PC) structures are fabricated by using NSL technique in this study, and the two-dimensional photonic crystal structures is acted as a scattering medium to extract the light to the out

碩士<br>國立臺灣大學<br>應用力學研究所<br>97<br>We attempted to manufacture nano-scale structures which were applied in the organic solar cell in this thesis, and further we used the simulation to discuss the functions of the metallic nanostructures as surface plasmon polariton (SPP) effect and the light scattering effect. It was anticipated to utilize the enhancement of power conversion efficiency in organic solar cell. In the theoretical part, we used finite difference time domain (FDTD) to calculate the electromagnetic fields and data analysis by using MATLAB or Sigmaplot, and then confirmed the influence

Abstract:
碩士<br>元智大學<br>光電工程學系<br>105<br>This study adopted a chemical solution technique to prepare a back-contact bottom electrode consisting of three-dimensional ZnO nanostructures. The electrode exhibited dye adsorption and light-scattering characteristics for enhancing the photoelectric conversion efficiency and wide-angle incident light applications of dye-sensitized solar cells. This study used the finite-difference time-domain method to simulate the light scattering of flower-like nanostructure and nanorod structure. The results indicated that the light scattering of flower-like nanostructure is
