AB  - An aqueous solution-based doping strategy was developed for controlled doping 
      impurity atoms into a ZnO nanowire (NW) lattice. Through this approach, 
      antimony-doped ZnO NWs were successfully synthesized in an aqueous solution 
      containing zinc nitrate and hexamethylenetetramine with antimony acetate as the 
      dopant source. By introducing glycolate ions into the solution, a soluble 
      antimony precursor (antimony glycolate) was formed and a good NW morphology with 
      a controlled antimony doping concentration was successfully achieved. A doping 
      concentration study suggested an antimony glycolate absorption doping mechanism. 
      By fabricating and characterizing NW-based field effect transistors (FETs), 
      stable p-type conductivity was observed. A field effect mobility of 1.2 cm(2) 
      V(-1) s(-1) and a carrier concentration of 6 x 10(17) cm(-3) were achieved. 
      Electrostatic force microscopy (EFM) characterization on doped and undoped ZnO 
      NWs further illustrated the shift of the metal-semiconductor barrier due to Sb 
      doping. This work provided an effective large-scale synthesis strategy for doping 
      ZnO NWs in aqueous solution.
