    A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as resistivity falls as its temperature rises; metals are the opposite. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal two differently-doped regions exist in the. Semiconducting SWNTs (s-SWNTs) are also considered an alternative to traditional silicon-based semiconductors. However, large-scale, as-produced SWNTs have poor solubility, and they are mixtures of metallic SWNTs (m-SWNTs) and s-SWNTs, which limits their practical applications.

    Nobel Lecture: Semiconducting and metallic polymers: The fourth generation of polymeric materials. When asked to explain the importance of the discovery of conducting polymers, I offer two basic answers: first they did not (could not?) exist, and second, that they offer a unique combination of properties not available from any other known materials. The first expresses an intellectual challenge; .

Heeger, Niyazi Serdar Sariciftci, Ebinazar B. Namdas. Conducting and Semiconducting and metallic polymers book (conjugated) polymers have a unique set of properties, combining the electronic properties of metals and semiconductors with the processing advantages and mechanical properties of polymers.

Now, thirty-five years after their discovery, metallic conducting polymers have been demonstrated in the laboratory to have electrical conductivities approaching that of copper.

This Nobel Lecture, presented in Stockholm on December 8,summarizes the discovery and development of the field of semiconducting and metallic polymers.

The field of semiconducting polymers has attracted many researchers from a diversity of disciplines. While, on the one hand, some of the foreseen applications are already being realized in industrial products, there is, on the other hand, still a deficient knowledge of the basic phenomena.

Metallic polymers have a lower density of electrons; both the length of the repeat unit along the chain and the inter-chain spacing are relatively large compared to the interatomic distances in conventional metals.

Typically, therefore, for metallic polymers N is of order 2×10 21 to 5×10 21 cm − by: Semiconducting and Metallic Polymers. Polymers are lightweight, flexible, solution-processable materials that are promising for low-cost printed electronics as well as for mass-produced and large-area applications.

Previous studies. ducting polymers is determined by the chain symmetry (i.e., the number and kind of atoms within the repeat unit), with the result that such polymers can exhibit semiconducting or even metallic properties.

Some of the semiconducting polymers can be doped with p- or n-type organic or inorganic dopants such as PClO 4, FeCl 3, iodine, alkali ions, leads to a few orders of magnitude increase of electrical conductivity and at the same time to a change in their linear optical properties associated with the creation of a charge transfer band by adding or taking from the polymer backbone an.

SEMICONDUCTING AND METALLIC POLYMERS: THE FOURTH GENERATION OF POLYMERIC MATERIALS Nobel Lecture, December 8, by ALAN J. HEEGER Department of Physics, Materials Department, Institute for Polymers and Organic Solids, University of California at Santa Barbara, Santa Barbara, CAUSA.

INTRODUCTION. This book reviews the current understanding of electronic, optical and magnetic properties of conjugated polymers in both the semiconducting and metallic states.

It introduces in particular novel phenomena and concepts in these quasi­ one-dimensional materials that differ from the well-established concepts valid for crystalline semiconductors.

Polymers commonly are semiconducting or insulating because of a sizable energy gap in the density of states around the Fermi level. Semiconducting and metallic polymers.

Organic semiconductors are solids whose building blocks are pi-bonded molecules or polymers made up by carbon and hydrogen atoms and – at times – heteroatoms such as nitrogen, sulfur and exist in form of molecular crystals or amorphous thin general, they are electrical insulators, but become semiconducting when charges are either injected from appropriate electrodes.

In the latter case, the award recognized the “discovery and development of conductive polymers”, which circumscribes well the subject of this new text: Semiconducting and Metallic Polymers. Heeger, Sariciftci, and Namdas have combined their experiences to describe for us the fundamental physics of conducting polymers (chapters 1–8), the.
