• Interesting and Enhanced Properties
• Unique hybrid nanostructures by design (1D-3D)
• Perfectly ordered and uniform size
• Solution processible thin films
• Large blue-shift due to very strong quantum
  confinement effect comparable to those of the
  smallest colloidal QDs
• Widely and systematically tunable band gaps
• Low effective e/h masses, high mobility expected
• High absorption coefficients (an order of
  magnitude higher compared to parent bulk)
• High exciton binding energies (10 time of those
  of parent bulk)
• Enhanced nonlinear optical behavior
• Strong photoluminescence (PL) emission
• Light weight, low cost, flexibility and stability
