Definition

Cross section of metal-oxide semiconductor field effect transistor.

An organic field effect transistor is a field effect transistor that uses an organic semiconductor in its channel. The advantages of using an organic are their low cost and ease of fabrication, especially for complex geometries. The most popularly used organic semiconductor for this application is pentacene.

The structure of pentacene, a common organic semiconductor.

Applications

Micelles have various applications, that are similar to the applications of surfactants. In biology, they are essential for dissolving any fats, or fat soluble vitamins in the body. Also, they are used in detergents to help cut away grease, again using their dissolving properties.

Reverse Micelles

Reverse micelles are the opposite of typical micelles - they form in a hydrophobic environment. These micelles have the hydrophilic heads aggregating in the center of the sphere, with the hydrophobic tailes pointing outwards. These micelle are used to form miniature test tubes because they create a nanoscale hydrophilic environment at their center where reactions can occur. One application of these is the formation of quantum dots at the center of these reverse micelles.
