Abstract:
Provided are a cooling device coated with carbon nanotubes and method of manufacturing the same. Carbon nanotubes are dispersively coated on a surface of the cooling device that radiates generated by a predetermined apparatus or component through thermal exchange. Thus, a carbon nanotube structure is formed so that the cooling device can improve in a thermal radiation characteristic and become small-sized. As a result, electronic devices can be downscaled and heat generated by a highly integrated electronic circuit chip can be effectively radiated, thus increasing lifetime and performance of an operating circuit.
Abstract:
Provided is a method of forming electron emitter tips for a field emission display device (FED) using copper-carbon nanotube composite electroplating. In the method, a cathode substrate having a surface on which a copper seed layer is defined is provided. The cathode substrate is dipped along with an anode substrate in an electroplating tank that is filled with an electroplating solution containing carbon nanotubes and a copper electrolytic solution. Thereafter, a copper-carbon nanotube composite is electroplated on the cathode substrate by supplying power to the cathode substrate and the anode substrate. By forming the electron emitter tips using the copper-carbon nanotube composite electroplating, an FED having a good adhesion of carbon nanotubes with the substrate can be fabricated. Also, the FED can have high luminance and a long lifetime and consume low power.

Provided are a low-temperature formation method for emitter tips including copper oxide nanowires or copper nanowires and a display device or a light source manufactured using the same. The low-temperature formation method includes preparing a substrate having an exposed copper surface. The copper surface contacts an oxide solution at a low temperature of 100 °C or less to grow copper oxide nanowires on the surface of the substrate. Optionally, a reduction gas or a heat is supplied to the copper oxide nanowires, or plasma processing is performed on the copper oxide nanowires, thereby reducing the copper oxide anonwires to copper nanowires. Thus, emitter tips including copper oxide nanowires or copper nanowires are formed densely at a low temperature such that the emitter tips have a shape and length suitable for emission of electrons.
