Electron Transport in Nanostructures and Mesoscopic Devices

Product Description
This book introduces researchers and students to the physical principles which govern the operation of solid-state devices whose overall length is smaller than the electron mean free path. In quantum systems such as these, electron wave behavior prevails, and transport properties must be assessed by calculating transmission amplitudes rather than microscopic conductivity. Emphasis is placed on detailing the physical laws that apply under these circumstances, and on giving a clear account of the most important phenomena. The coverage is comprehensive, with mathematics and theoretical material systematically kept at the most accessible level. The various physical effects are clearly differentiated, ranging from transmission formalism to the Coulomb blockade effect and current noise fluctuations. Practical exercises and solutions have also been included to facilitate the reader’s understanding.

Fabrication of Pt/C Nanofiber Electrode for Fuel Cell Application

Product Description
Triethylamine catalyst was used to increase the molecular weight of poly(amic acid). In electrospinning, diameter of PAA nanofibers was controlled by molecular weight of poly(amic acid) and concentration of poly(amic acid)/N-N dimethylformamide solution. The diameters of polyimide based carbon nanofibers reached to a minimum value of around 100 nm. The conductivity of the carbon nanofiber papers increased with the decreasing of fiber diameters, while the mechanical strength of polyimide and carbon nanofiber paper was diameter independent. Further more, Pt was successfully impregnated in carbon nanofiber. Reduction accompanied with carbonization in Ar gas at up to 1000 degree C produced small and well-dispersed Pt nanoparticles (3-5 nm). Carbon dioxide treatment exhibited the effective ability of removal of carbonaceous overlayers to promise a potential enhancement Pt catalyst activity. The reduction rate of Pt ion is different at heating rate of 2 and 5 degree C/min. Thus, the heating rate and time at high temperature strongly affected Pt nanoparticle size.
