Graphene has a huge variety of unique optoelectronic properties. Its recent rapid emergence and demonstrable richness in electron transport has been unprecedented. This atomically thin, ordered structure has exceptionally high attainable aspect ratios - potentially higher even than that of carbon nanotubes - whilst defective edge terminations rich in dangling bonds render it superior to metallic nanowires;...
A new structure of under-gate carbon nanotube (CNT) field emission display (FED)panel is proposed in this paper with normally-on driving scheme. In this structure, the gate electrode is still located beneath the cathode with the cathode and focus electrode arranged alternately. The effect of the under-gate is to prevent the field emission when the negative voltage is applied on the gate electrode...
With all the advantages of the FED, surface conduction electron emission display (SED), which is developed by the Canon-Toshiba with a 36 inch diagonal, has additional superiorities compared to the foregoing displays as better brightness, power consumption and response time.Surface conduction emission is a planar-triode configuration field emission, which refers to electron emission from a roughed...
Hopping field emission display (HopFED) which is based on secondary electron emission is a novel structure of field emission display. Compared to the conventional structures, this new type has several advantages. The brightness, the luminance uniformity and the profile of the spot on the screen have been improved. To simplify the fabrication process, the gate electrode is deposited on the bottom surface...
A carbon nanotube field emission display (CNT-FED) composed of a cathode, a gate electrode and an anode is fabricated. The device is analyzed by IR spectra. The gate electrode was fabricated using corrosion reaction. The luminance of the triode structure FED is measured
