Electric-field-induced effective anchoring energy in nematic liquid crystal is investigated taking surface and flexoelectric polarization into consideration. The analytical expressions of effective anchoring energy for both bottom and upper substrate containing these two polarizations are derived. The effective anchoring strength for both bottom and upper substrate is also obtained by means of a systematic method which is relevant to magnitude of two polarizations and determined by the applied voltage U. Applying the obtained expressions into an original weak anchoring hybrid aligned nematic cell the effective anchoring strength are determined with the different magnitudes of two polarizations and the different applied voltage U.

This study explores an electrophoretic process to selectively assemble carbon nanotube emitters into normal triode structure for triode type carbon nanotube field emission display cathode. In this process the carbon nanotubes are migrated and deposited into triode structure by an applied voltage between the gate electrode and cathode electrod. The applied voltage is also used to keep the carbon nanotubes off adsorption on the gate electrode. The experiment results show that the carbon nanotubes are selectively defined inside of gate holes and each hole has the same packing density. The process which is low cost and easily scaling up is an alternative method to prepare triode type carbon nanotube field emission display cathode.

The threshold voltage of a-Si: H/SiNx TFT will shift under long time gate bias stress it is mostly leaded by charge trapping in gate insulator and defect creation in semiconductor. And it is hard to be applied in AMOLED for TFT because of its threshold voltage shift. In allusion to the phenomenon of charge trapping a series of SiNx insulating films in different N/Si(0. 87 -1.68) ratio were deposited by PECVD in this paper controlling different flow ratio of source gas SiH4 and NH3 and a great deal of tests (ellipsometer infrared absorption (FTIR) and Electron Dispersion Spectrum (EDS) test ) were done on these samples. Based on these SiNx insulators three different capacitance samples in MIS structure were done degraded experiments and C-V tests on these samples were done. The C-V curve shift of capacitance which contained SiNx with slightly N-rich(N/Si is bigger slightly than 1. 33) was not evident before and after degradation this result indicated that the defect density of this type SiN x was smaller and could restrain charge chapping in the interface of a-Si:H/SiNx effectively. So that as gate insulator of TFT SiN x with slightly N-rich could decrease the threshold voltage shift of TFT and enhance its stability effectively.

Carbon nanotubes have been attracting attention because of their unique physical properties and their application potential for field emission cathode. Carbon nanotubes possess the following properties favorable for field emission material such as a high aspect ratio and sharp tip high chemical stability high mechanical strength stable at high temperature. Some research works on carbon nanotubes field emitter and field emission display have been reported. Here a kind of carbon microtubes and its field emission properties are introduced. They have some different properties with carbon nanotubes and the density is lower than carbon nanotubes bundles. These carbon microtubes are directly synthesized by liquidoid epitaxy method on silicon substrates at low temperature. The field emission properties of carbon microtubes are reported too. Carbon microtubes film is synthesized in liquid by electrolysis. The graphite plate is as anode and n-silicon substrate with resistivity of 4-8 cm is as cathode. The electrolysis current is about 5-8mA/cm2 and applied voltage is 800-1500V. Temperatures of the methanol base solution is maintained at 60C in process of deposition of carbon microtubes. Carbon microtubes film is observed by scanning electron microscopy(SEM) as shown in fig.1(a b). The wall's thickness of carbon microtube is about 60nm. The diameter of carbon microtube is about 0.8 m. Raman spectrum of carbon microtubes film shows the two peaks at 1342and 1560cm-1. The field emission properties of carbon microtubes are measured in high vacuum chamber(10-5Pa). The emission area of carbon microtubes is 0.5cm 0.5cm. The threshold of field emission of the carbon microtubes film is about 3.6V/ m. Field emission property of carbon microtubes film is shown in fig.2. Another when the electric field between anode and cathode is 10V/ m the electric field distribution on single carbon microtube is also given after calculation according to electric field theory. Fig 3 shows that electric field distribution vertical section on the of single carbon microtube top with 2 m of highness. These results may help us to understand field emission properties of carbon microtubes. According to research results it is found that liquidoid synthesis is simple method to produce carbon microtubes cold cathode material and the carbon microtubes have better field emission properties. 2005 IEEE.
