Unique physical and chemical features of nanomaterial’s when compared to the bulk have caused a great research interest. Presences of foreign atom or Impurities are reported to modify electronic, optical, and magnetic properties of bulk semiconductors (Surender Kumar et al 2012, Jin et al 2005). Recent years one-dimensional (1-D) nanostructures have been the focus of current researches due to their unique physical properties and potential applications in nanoscale optoelectronics (Wang et al 2009, Jun Pan et al 2012). Especially, the extraordinary lengths, flexibility and structure of the one dimensional nanowires, tubes and fibers can offer the required design of shape and size. Further, quantum effects are unique in 1D structure which leads to the variation in electronic properties.
