Description

technical field [0001] The invention relates to a method for preparing a carbon nitride / carbon nanotube diode with a nano junction, and a method for preparing a rectifier circuit and a logic gate circuit. Background technique [0002] With the development of electronic technology, the size of electronic devices is constantly shrinking. However, when the size of the device enters the nanometer scale from the micrometer, due to the influence of the quantum effect, the current inorganic device materials are no longer suitable. Carbon nanotubes and nanowires have good mechanical and electronic properties and become potential nano-device materials. Many nanoelectronic devices have been prepared by using carbon nanotubes and nanowires, such as molecular wires, differential resistors, diodes, room-temperature field-effect transistors, single-electron transistors, and memories (1: Hu, J.; Ouyang, M.; Yang, P .; Lieber, C.M. Nature, 1999, 399, 48.2: Zhen, Y.; Postma, W.Ch; Balents,...
