Semiconducting and metallic polymers by Alan J Heeger( Book )
5 editions published in 2010 in English and held by 168 WorldCat member libraries worldwide
"Conducting and semiconducting (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, and mechanical strengths exceeding that of steel, a remarkable achievement

Program for Research in Conducting Polymers by Alan J Heeger( Book )
4 editions published between 1991 and 1992 in English and held by 4 WorldCat member libraries worldwide
This broad based interdisciplinary program, involved synthesis and characterization of new conducting polymers, processing of these conducting polymers into highly oriented fibers and films, and measurement of the electrical and optical properties of the materials. At the beginning of those period of ONR sponsored research, conducting polymers were available in mg quantities, they were unstable and they were intractable. Today, large quantities are available (in some cases in commercial scale), and there are specific systems which are both stable and processible. Moreover, it is now clear (largely as a result of the effort at UCSB) that the desired combination of properties is available: Electrical and Optical Properties of Metals and Semiconductors and Mechanical Properties and Processing Advantages of Polymers
Organic Metals and Semiconductors: Polyacetylene, (CH)x, and Its Derivatives ( Book )
3 editions published in 1979 in English and held by 3 WorldCat member libraries worldwide
Both cis- and trans-forms of polyacetylene, (CH)(x), may prepared as silvery, flexible polycrystalline, semiconducting films. The cis-films can be stretched to over three times their original length with partial alignment of the (CH)(x) fibrils. Through chemical or electrochemical doping, the electrical conductivity of the films can be increased over twelve orders of magnitude with properties ranging from insulator to semiconductor to metal. By the use of donors or acceptors, n-type or p-type polymer, respectively, is produced. Photoelectrochemical photovoltaic cells have been fabricated using (CH)(x) as the active photoelectrode
Nonlinear Optical Properties of Semiconducting Polymers ( Book )
3 editions published between 1989 and 1990 in English and held by 3 WorldCat member libraries worldwide
This program focused on the nonlinear optical properties of semiconducting conjugated polymers. Specific emphasis was on fast time (picosecond regime) measurements of the photoconductivity of semiconducting polymers and on nonlinear optics (NLO) measurements related to the mechanism and origin of the nonlinearity and on attempts to optimize the magnitude of the nonlinear response. In the transient photoconductivity area, these publications focused on the carrier generation, mobility and carrier recombination processes. The results are of particular importance; by implementing the Auston switch technique (to enable fast transient photoconductivity measurements with temporal resolution <100 ps), we were able to explore the photogeneration process early times. The results have caused a reevaluation of the previously accepted Onsager geminate recombination process. We succeeded in demonstrating that for conjugated polymers the nonlinear response is highly anisotropic with substantial nonlinearity only when the pump is polarized along the direction parallel to the polymer backbone. In attempting to sort out the NLO mechanism we carried out comparative studies on cis and trans-polyacetylene. The larger NLO response from the trans-isomer (larger by at least a factor of 20) shows the importance of the degerate ground state
