Nanowires methods for producing the nanowires are provided. The nanowires include a plurality of metal nanodots uniformly disposed therein, and a core portion, wherein each of the plurality of metal nanodots is coupled to the core portion. According to the method, metal nanodots can be uniformly disposed in the nanowires, and nanowires having various physical properties can be produced by controlling the size and interval of the nanodots. Therefore, the nanowires can be effectively used in a variety of applications, including electronic devices, such as field effect transistors (FETs), sensors, photodetectors, light emitting diodes (LEDs), and laser diodes (LDs).
