Researchers Map Electronic Structure of Plastic Semiconductors
Scientists have detailed how benzene rings function as building blocks in conjugated polymers, materials that behave like semiconductors and can be engineered into conductors. The findings could accelerate development of cheaper, more efficient organic electronics for displays, transistors, and next-generation devices.
Originaltitel: How the phenyle rings (benzene) act as building blocks in pi conjugated polymers
<p>Organic conjugated polymers have the electronic structure of semiconductors and can be doped to become good conductors (1). Conjugated polymers are now used as active materials in a wide variety of prototype applications such as light emitting diodes [2] and organic transistors [3,4]. Most of the interesting chemistry and physics of conjugated polymers is associated with the details of the electronic structure at the valence and conduction band edges and, in this connection, various electron spectroscopies can be used as tools for diagnosis of the relevant electronic and geometric properties....</p>
