Fabrication and Characterization of Organic and Inorganic Linear Nanostructures

  • Research was undertaken into the organic semiconductors tris(8- hydroxyquinoline)aluminum (Alq3) as well as bis(8-hydroxyquinoline)zinc (Znq2) to the effect of improving achievable morphological control using an inexpensive evaporation based solution synthesis method. By varying experimental parameters such as ambient temperature, vapour pressure, choice of anti-solvent used and exposure time, growth and nucleation were optimized so as to produce organic single crystals. Two methods were discovered to grow arrays of vertically-aligned Alq3 nano/micro rods out of a thin film of Alq3. Afterward, dielectrophoresis (DEP) was studied as a means to align linear nanostructures onto testing pads for characterization. To that effect, a DEP alignment platform containing seventy-four testing devices was designed and then constructed using microfabrication techniques such as electron beam evaporation and photolithography. Alignment of individual nanowires have been successful, and electrical measurements have been performed on p-type copper oxide yielding a hole mobility of 25.5 cm2/Vs.
