| 中文摘要 | 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxdiazole (pbd) is a good electron-transporting material and can form single crystals from solution. in this work, solution cast pbd single crystals with different crystallographic axes (b, c) perpendicular to the au/s substrates in large area are achieved by controlling the rate of solvent evaporation in the presence and absence of external electrostatic field, respectively. the orientation of these single crystals on au/s substrate was characterized by transmission electron microscopy (tem) and atomic force microscopy (afm). conducting probe atomic force microscopy (cp-afm) was used to measure the charge transport characteristics of pbd single crystals grown on au/s substrates. transport was measured perpendicular to the substrate between the cp-afm tip and the au/s substrate. the electron mobility of 3 x 10(-3) cm(2)/(v s) for pbd single crystal along crystallographic b-axis is determined. and the electron mobility of pbd single crystal along the c-axis is about 2 orders of magnitude higher than that along the b-axis due to the anisotropic charge transport at the low voltage region. |
