Organic Semiconductor Materials for Future Electronics

Organic semiconductors are very promising candidates as starting materials for the manufacture of cheap, large area and flexible electronic components such as transistors, diodes and sensors on a scale ranging from micro to nano. However, there are lots of challenges in this field that receive substantial attention from researchers in recent years. Due to poor van der Waals interaction between molecules, electrical conductivity of these materials is not as high as other materials such as Si, Ge etc which are extensively being using in microelectronic industries. Nevertheless, stability of these materials has been another issue that needs to be improved through research and development. In spite of all these, these molecules show promise to be competitive candidates to replace some of the electronic devices that we are using present days. Over the years, tremendous progress has been achieved. However, much more of the work demonstrated in the laboratory needs to be translated into reliable and reproducible products, which can be manufactured cheaply. In this article, I intend to describe the important electronic devices based on organic semiconductors with specific focusing on the challenges and advantages.
