limitations at early stage
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.
