Abstract
A physiochemical process for preparing nm-class conducting wire whose diameter and length are controllable includes such steps as adsorbing the thiols compound on the base of scanning probe microscope, using the probe tip of scanning microscope to dip the solution of nm-class metal or alloy particles, and scratching line. Under the capillary action, said nm-class particles flow toward the base to generate chemical metal-sulfur bond, resulting in nm conducting wire.
Description
The invention belongs to the physical chemistry preparation method of diameter and length controlled nm-class conducting wire.
The core of nanosecond science and technology is microminiaturizations of device, and nano-device or device that molecular motor, nano-transistor, nanometer light emitting diode etc. have specific function are seen in report.Each component-assembled of these nanodevices will be become the integral body with specific function, linkage unit-nm-class conducting wire is essential, thereby the preparation of nm-class conducting wire is particularly important.The preparation of nm-class conducting wire relatively lags behind with respect to the manufacturing of nano-device or device.The preparation of nm-class conducting wire at present mainly concentrates on following several method: one. the template construction from part, as the template synthesis of nano traverse method of the common report of U.S. scientific magazine Tuominen on December 15th, 2000 and Russell group; Two. the auxiliary drawing process of template assembling electric field, as the AC field pulling method of reports such as U.S.'s Applied Physics wall bulletin the 77 volume the 8th phase P.A.Smith in 2000.The vary in diameter scope of the nm-class conducting wire that the template assemble method generates is big, does not wait from several nanometers to micron order, and the time that length is also assembled, the concentration of solution and character etc. influence and comes and go.The nm-class conducting wire diameter that the auxiliary drawing process of template assembling electric field generates is thicker, and not easily separated.
The physical chemistry preparation method who the purpose of this invention is to provide a kind of controllable nm-class conducting wire.This method is with scanning probe microscopy substrate absorption mercaptan compound, dip in the solution of getting the metal or metal alloy nano particle with the scanning probe microscopy needle point then, carry out the lines delineation, because the metal or metal alloy nano particle on the capillarity needle point flows to substrate and forms gold-sulfur bond with mercaptan, form nm-class conducting wire.
Because metal or metal alloy nano particle and suprabasil mercaptan form the metal-sulfur chemical bond, guaranteed to be closely aligned mutually between the nano particle; Diameter is controlled, only depends on diameter of nano particles, and length can be delineated the length of nano particle lines as required.
The present invention is earlier with scanning probe microscopy substrate absorption mercaptan compound; The method of absorption mercaptan compound mainly contains two kinds, 1) infusion method, as Stearyl mercaptan, treat standby after the scan-probe substrate being immersed in the Stearyl mercaptan saturated solution of second cyanogen 0.5-10 minute and drying up; 2) vapour deposition process such as 16-sulfydryl hexadecanoic acid, places airtight 16-sulfydryl hexadecanoic acid gas cell with 50-80 ℃ of heating 10-30 minute the scan-probe substrate, is cooled to after the room temperature standby; Select to form with mercaptan compound the metal or metal alloy nano particle of chemical bond then, be specially gold, palladium, platinum, silver, copper, cadmium, silver-platinum, copper-palladium, nickel-copper, Yin-Jin, nickel-palladium or silver-palladium, preparation process is to dip in the sol solution that cut-off directly is the metal or metal alloy nano particle of 1.25-147 nanometer with the scanning probe microscopy needle point, carry out the lines delineation, control length as required.
