• 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.
