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.
