SURFACE MODIFYING METHOD OF SnO2 NANOWIRE USING PULSED LASER AND THE SURFACE MODIFIED SnO2 NANOWIRE STRUCTURE THEREOF AND GAS SENSOR COMPRISING THE SURFACE MODIFIED SnO2 NANOWIRE STRUCTURE

摘要

One embodiment of the present invention provides a method for modifying the surface of tin oxide nanowires using a pulse laser, a surface-modified tin oxide nanowire structure, and a gas sensor including the surface-modified tin oxide nanowire structure. Specifically, by modifying the surface by irradiating a pulse laser on the tin oxide nanowires, a plurality of tin oxide (SnO) nanoparticles are provided on the surface, thereby maintaining tin oxide nanowires' unique properties while having a large surface area tin oxide Since a nanowire structure can be provided, it can be actively used as a gas sensor with excellent sensitivity.
