Fig. 3

a, b Quantitative views of the length and diameter of ZnO nanorods with an increase of NH4H2(PO4)2 M ratio, respectively. ce The changes in doping concentration, Hall coefficient, and mobility of the nanorods as functions of NH4H2(PO4)2 M ratio, respectively. Conductivity changed from negative to positive when NH4H2(PO4)2 M ratio is higher than 0.3% approximately. The decrease in the doping concentration of the nanorods corresponding to 1% of NH4H2(PO4)2 M ratio is due to the self-compensation effect beyond the solubility limit of phosphorus in the ZnO nanorods
