Description:
Based on experimental observation and theoretical analysis, it explicates that light emission of a carbon nanotube-field emission display (CNT-FED) is mainly caused by electron bombardment on the phosphour if the level of vacuum ranges from 10^-^4 to 5Pa. In this case, light emission of the phosphour excited by ultraviolet (UV) light derived from gas discharge cannot be observed. If vacuum level is greater than 5Pa, no emitted light is observed, since a large amount of gas ionisation reduces the electric potential difference between the cathode and the anode. To analyze collision between electron and gas under field emission conditions, a mathematical and physical model was built. Based on this model the number of electron-gas collisions is calculated. Calculations results indicate that the product of gas pressure and distance between the electrodes (pd) is a better parameter to characterize the effect of vacuum level for FED than gas pressure only. Calculations results also show that if the distance between the cathode and the anode is increased, it should be to improve the vacuum level to obtain the same effect.

Science of Engineering Materials and Carbon Nanotubes

Product Description
Part I provides the essential classical and quantum laws on which the correlation between properties and structures of materials is explained. It covers the traditional engineering materials, metals and alloys, semiconductors, polymers, dielectrics, amorphous solids, superconductors and materials for magnetic, nuclear, space and laser applications. The recent discovery of carbon nanotubes (CNT) has led to nanotechnology and exciting applications in biology, medicine, textiles, energy, transportation and electronic devices. An update to this edition as Part II of the book is the physical description of CNT, the method of their production, the classical and quantum aspects of their properties and the way these differ from the three-dimensional materials discussed in Part I. The author accounts for the difference in properties like electrical and thermal conduction in copper and carbon nanotubes on models that differ due to dimensionality of the material.
