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.
