Organic semiconductors are inexpensive hence easy to fabricate device out of them, they can be modulated in various desirable way like in electronic properties of band gap, can be made transparent which is good for Optical electrodes, flexible. Because of these modulation they are finding their application in wide varieties of area. Of course they are very attractive choice for researchers now a days.
The fundamental difference between inorganic and organic semiconductors is in the charge
transport mechanism. In the former case electrons moving in wide bands as delocalized plane waves are subjected to very limited scattering, and hence, feature relatively high mobility (e.g. ~1.5 x103 cm2V-1s-1 in Si at room temperature). In the case of organic semiconductors, the charge transport is based on carriers hopping between localized states associated with organic molecules. In the process electrons undergo significant scattering which results in very low electron mobility in organic semiconductors (~1-3 cm2V-1s-1).
Commonly doped silicon is used to make semiconductors, but advancements in organic electronics now mean that semiconductors can be made from molecules made from elements such as carbon, hydrogen, oxygen, sulphur, nitrogen and a few others.

Germenium and silicon are the examples of Semiconductors.
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.

semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors

Group 14 elements, mainly silicon or germanium are semiconductors. If they are dopped with group 13 elements such as gallium / indium or with group 15 elements such as arsenic / antimony, then the conducting ability increases.
Conductive plastic is a more organic polymers that conducts a type of bondage. Such compounds are known to have metallic conductivity or can be semiconductors.
