Inorganic Vs. OrganicMaterial Properties

Limitations At Early Stage

• Organic materials have often proved to be
  unstable.
• Making reliable electrical contacts to organic
  thin films is difficult.
• When exposed to air, water, or ultraviolet light,
  their electronic properties can degrade rapidly.
• The low carrier mobilities characteristic of
  organic materials obviates their use in
  high-frequency (greater than 10 MHz) applications.

These shortcomings are compounded by the
difficulty of both purifying and doping the
materials.
