Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an InSb nanoparticle to be used for a semiconductor, or the like.[0003]2. Description of the Related Art[0004]Since the InSb nanoparticles have a mobility of about 78,000 cm2 / Vs, which is larger than the mobility of Si of 1,450 cm2 / Vs, attention is paid thereto for the utilization to a semiconductor so that various synthesis methods have been studied. The synthesis methods for the inorganic nanoparticles can be roughly classified into the solid phase method, the liquid phase method and the gas phase method. As to the synthesis methods for the InSb nanoparticles, the liquid phase method and the gas phase method are known.[0005]As to the synthesis method using the liquid phase method, for example, Solvothermal Reduction Synthesis reports the synthesis of the InSb nanoparticles of a 30 nm to 50 nm particle size by heating In and SbCl3 to 180° C. to 300° C. with a benzene provided as the sol...

Benefits of technology

The present invention provides an InSb nanoparticle, an InSb nanoparticle dispersion, and a method for producing an InSb nanoparticle. The InSb nanoparticle has the ability to be dispersed and independent in a dispersion medium, making it easy to form film or patterns on the surface. The nanoparticle has residues of a hydrophilic group and a hydrophobic group, which prevents aggregation and facilitates patterning. The dispersion medium can be a nonpolar solvent or a polar solvent, depending on the configuration. The invention also provides a method for producing an InSb nanoparticle using the hot soap method. Overall, the invention provides a simple and effective way to produce and disperse InSb nanoparticles for various applications.

Problems solved by technology

However, it is difficult to use the secondarily aggregated InSb nanoparticles as mentioned above to the ink jet method or the printing method because an even coating film can hardly be obtained.

Furthermore, blockage of the nozzle is generated in the case of the ink jet method, thus it is problematic.

However, according to these methods, since the InSb nanoparticles are fixed on the substrate, also in this case, it can hardly be used for the ink jet method or the printing method because it is difficult to disperse the InSb nanoparticles in a dispersion medium at the time of preparing the coating solution.

Moreover, a problem is also involved in that the substrates capable of forming the InSb nanoparticles are limited and expensive.

Therefore, since the InSb nanoparticles are fixed on the SiO2 film, also as in the case mentioned above, it can hardly be used for the ink jet method or the printing method.

However, according to the method, not only the InSb nanoparticles but also the Sb nanoparticles are formed, and thus it is difficult to obtain only the InSb nanoparticles.

Moreover, since the InSb nanoparticles are fixed on the amorphous carbon film, as in the case, it can hardly be used for the ink jet method of the printing method.

Furthermore, another problem is involved in that the substrates capable of forming the InSb nanoparticles are limited.
