Organic semiconducting devices have many positive attributes, such as their low cost, high flexibility, light weight, and ease of processing. However, one drawback of organic semiconductors is that they generally have a low electron mobility, resulting in a weak current and poor conductivity.

In a new study, scientists from Taiwan have designed and built an organic semiconductor transistor with a mobility that is 2-3 orders of magnitude higher than that of conventional organic semiconductor transistors. The benefits of a high mobility could extend to a wide range of applications, such as organic LED displays, organic solar cells, and organic field-effect transistors.

The researchers, in a collaboration of the groups of Prof. CD Chen from Academia Sinica and Prof. MT Lin from National Taiwan University, have published their paper on the new high-mobility organic semiconductor in a recent issue of Applied Physics Letters.
