In this paper the thermal conductivities of monocrystal carbon, silicon, and germanium nanometer thin film are simulated respectively using non-equilibrium molecular dynamics (NEMD) method and corresponding Tersoff potential energy function. The simulation results indicate that the thermal conductivities of those nanometer thin films are obviously lower than the corresponding thermal conductivities...
Due to the trade secrets and intellectual property, there are still many aspects of MEMS switches which are not understand well and are currently under investigation. In this paper, our report shows that MEMS can be released using O2 and a little carbon powder at the same time. The relationship between the removing polyimide time and the cure temperature is presented using carbon powder in the quartz...
A pyrolytic carbon film electrode was fabricated by the low temperature chemical vapor deposition (CVD) method. This report deals with the preparation and electrochemical behavior of this carbon film. To characterize the surface structure, scanning electron microscopy was applied. Also, cyclic voltammetry and chronocoulometery were applied to evaluate the electrochemical properties
In order to understand the formation mechanism of nano- materials during the arc discharge in liquid, serial experiments were conducted on synthesis of nano-materials by arc discharge both in water and in liquid nitrogen. Previous research showed that the stability of arc discharge affected the nano-products significantly. In this paper, the cross magnetic field (CMF) was introduced to disturb the...
Polycrystalline diamond (poly-C) was used as a piezoresistive position sensor in a cochlear implant probe for its high piezoresistive sensitivity. Based on previous studies [Spelman, FA, 1999], the 3rd generation cochlear probe with poly-C position sensors were designed and fabricated with several new improvements for compatibility and integration with the Si-based bulk micromachining technology....
This paper reports the fabrication and experiment of a micro time of flight (TOF) mass spectrometer adopting a new ion generation method using a carbon nanostructure. The device is composed of an ion source and an ion separator. The ion source generates electrons by the field emission method. Carbon nanostructure has good field emission property. The emitted electrons collide with sample molecules...
Bio-fuel cell (BFC) using baker's yeast was constructed to examine electricity production. Glucose was used as fuel and electricity was produced by the overall redox reaction in the cell. Neoseptareg membrane was used as proton exchange membrane for separating an anodic compartment and a cathodic compartment. As electron mediator, methylene blue was used for transporting electron from yeast to electrode...
Nanoscale tweezers are integrated to deep reactive ion etching (DRIE)-processed microelectrodes by localized chemical vapor deposition using focused ion beam (FIB-CVD). The MEMS electrodes for electrostatic actuation of nano tweezers are fabricated on a heavily doped SOI wafer, which works as the interconnecting platform to control nanoscale device from macro-world. Unlike the carbon nano tube (CNT)-based...
