Abstract:
High performance/small package electronics create difficult thermal issues for integrated circuits. Challenges exist at material interfaces due to interfacial contact resistances. Multiwall carbon nanotube (MWCNT) arrays are considered to be excellent candidates for use as thermal interface materials (TIMs) due to outstanding thermal/mechanical properties. In this work, MWCNT array TIMs are analyzed in aluminum and carbon fiber composites via flash diffusivity analysis. The effect of TIM thickness, areal/bulk density, surface cleanliness, and volumetric packing fraction; along with the effect

Abstract:
The work presented in this thesis is concerned with pure, water-soluble multiwall carbon nanotube inks, in particular their use in the fabrication of inexpensive field emission (FE) cathodes. This work is divided into three parts. Firstly, with the aim of fabricating a transparent FE cathode, nanotube inks are spin-coated onto transparent substrates, which subsequently are subject to laser treatment. An improvement in the FE properties with increasing laser fluency is observed, resulting in threshold fields of less than 6 V/mum (glass substrates) and less than 0.5 V/mum (plastic substrates). S

Abstract:
Shrinking volume, coupled with higher performance, microprocessors and integrated circuits have led to serious heat dissipation issues. In an effort to mitigate the excessive amounts of waste heat and ensure electronic survivability, heat sinks and spreaders are incorporated into heat generating device structures. This inevitability creates a thermal pathway through an interface. Thermal interfaces can possess serious thermal resistances for heat conduction. The introduction of a thermal interface material (TIM) can drastically increase the thermal performance of the component. Exceptional the

Abstract:
Carbon nanotubes have been studied for nearly two decades and their amazing properties continue to spur intense investigation in the area of polymer composites. In terms of potential commercialization, mutiwall carbon nanotubes (MWCNTs) are currently the most prevalent and economically viable form of nanotubes. Uncovering innovative means to take full advantage of their properties remains a fundamental issue. In this thesis, viability of their use to reinforce polymeric systems is reported.

Lead-tin solder has been widely used as interconnection material in electronics packaging for a long time. In response to environmental legislation, the lead-tin alloys are being replaced with lead-free alloys and electrically conductive adhesives in consumer electronics. Lead-free solder usually require higher reflow temperatures than the traditional lead-tin alloys, which can cause die crack and board warpage in assembly process, thereby impacting the assembly yields. The high tin content in lead-free solder forms tin whiskers, which has the potential to cause short circuits failure. Conduct

Abstract:
Electroconductivity laser stimulation (irradiation) of composite layers based on carboxymethyl cellu-lose (CMC) and multiwalled carbon nanotubes (MWCNT) has been researched. The layers were deposited on the following substrates: flexible such as polyimide, polyester, aluminum foil paper, cotton fabric and shop paper (~80 g/m2]; hard substrates such as Si/SiΟ2 and cover glass. The conductivity of layers with thickness 0.5 10 μm was improved more on 500 % /(W/cm2) after laser stimulation (wavelength 970 nm, emission specific power PS~0.051 W/cm2, concentration C~0.05 wt.% MWCNT).

Abstract:
This work describes a glassy carbon electrode (GCE) modified by 4-((E)-(2-methyl-4-nitrophenylimino) methyl) benzene-1,2-diol (abbreviated as MBD) and multiwall carbon nanotubes (MWNT) as an electrochemical sensor for monitoring of levodopa (LD) concentration. Different electrochemical parameters of MBD were obtained at MWCNT-GCE by cyclic voltammetry. Also the electrocatalytic behavior of LD was investigated at the MBD-MWNT-GCE by cyclic voltammetry, chronoamperometry and differential pulse voltammetry. Using the electrocatalysis of LD V in phosphate buffer solution pH 7.0 on this modifi

Abstract:
The interwall spacing of multi-walled carbon nanotubes has an effect on their physical and chemical properties. Tubes with larger interwall spacing - compared to the spacing where the carbon atoms are in their natural distance to each other - are for instance expected to be mechanically less stable. Considering the MWCNT interwall spacing’s dependence on the tube size, three interesting previous studies with slightly different conclusions can be found. All of them conclude an increase of the interwall spacing with a decreasing tube size. We describe their analysis procedure, compare them to ea

Abstract:
A theoretical model is developed for calculating the sensitivity of resistive sensors based on aligned multiwall carbon nanotubes (MWCNT) embedded in the pores of alumina membranes. Aligned MWCNTs offer more surface area as each CNT acts as a landing site for detecting gas species. The MWCNTs behave as a p-type semiconducting layer; when the bus bar contacts are placed at either end of the top surface the resistance between the contacts responds to oxidizing (resistance decreases) and reducing gases (resistance increases). The model presented in this thesis aims to understand the device resist

The experimental results showed that the liquid crystal polymer (LCP) based MWCNT composites can exhibit a high SE of 38 dB ~ 45 dB within the frequency range of 1 GHz ~ 3 GHz.

碩士<br>中原大學<br>應用物理研究所<br>91<br>Recent studies in this laboratory indicate that multiwall carbon nanotubes (CNTs) as a dopant can enhance nonlinear optical properties of host liquid crystal (LC), because they can form charge-transfer (CT) complexes in the system. Evidence of existence of a third matter through intermolecular interaction in the solution is provided by the fact that neither the absorption spectrum nor the fluorescence spectrum of the solution is equal to the sum of that of liquid crystal and of multiwall carbon nanotubes. We found that the central wavelengths of the new bands d
