Organic and polymeric materzials have seen a tremendous growth in research in the last five years as potential electroactive elements in thin-film-transistor (TF T) applications. These are driven by the increasing interest in flat-panel-display applications, for which organic and polymeric materials offer strong promise in terms of properties, processability, cost, and compatibility with eventual lightweight, flexible plastic displays. In this review we summarize the current status of our knowledge on the science of these organic and polymeric semiconducting materials. Most of these are based on linear thiophenes, especially a-hexathienyl, which has elicited by far the most attention. Mobility values in the 10 22 -10 21 cm 2 ͞Vs and especially source-drain current on͞off ratios of up to 10 6 make this a highly promising potential alternative to amorphous silicon. Other thienyl compounds are also discussed, as are polymeric analogues. A brief discussion of technological potential, limitations, and problems that need to be overcome is given at the end.

“…The wide variety of inherently conducting polymers has been demonstrated to work in such electronic devices as field effect transistors [1], light emitting diodes [2], photovoltaic cells [3,4] etc. Combining such polymers with plastic optical materials would enable to prepare all organic opto-electronic devices, that could be further used in fiber-optic sensor systems as light detectors etc.…”

“…Besides, they are more stable than metals in an electrochemical environment, are chemically inert and exhibit a density of states distribution similar to that of a metal. Deposition of monomolecular [113], PEDOT-PSS (poly-ethylene-dioxythiophene stabilized with polystyrene-sulphonic acid) [114], and polypyrrole [115]. It is our opinion that these electrodes should be explored in more detail for applications in molecular electronics to give a step towards metal-free molecular electronic devices.…”

Molecular electronics [1,2] is a promising field of research based on the idea that a single molecule or two dimensional assemblies of molecules (monomolecular films) can work as wires, switches, rectifiers, etc. Molecules are the smallest functional units and therefore it is expected that the use of molecules will permit to catch up with the limits of miniaturization (MM: more Moore), with an increase in device density by a factor of several orders of magnitude compared to today's state of the art. At the same time due to quantum effects novel and remarkable properties of organic and organometallic compounds at the nanoscale devices will result in increased performance (MtM: more than Moore) together with the appearance of new functions not possible with conventional semiconductors, and also cheaper devices due to the non-dependence of expensive materials used today in CMOS (complementary metal-oxide semiconductor) technology such as hafnium oxide. Nowadays, the number of research groups from different disciplines of science contributing to molecular electronics is gradually growing, and this field is becoming of great scientific and technological interest [1,3-8]. Since the seminal work of Aviram and Ratner in 1974 who firstly suggested that a single molecule could function as a rectifier [9], molecules have been experimentally demonstrated to work as switches, molecular wires or rectifiers, and a new field of opportunities is opened due to the understanding of electron transport through single entities or assemblies of molecules and expansion towards work on molecular spintronics, vibronic effects, excitation of the molecular junction with polarized light, quantum interference and decoherence, molecular chirality, molecular stretching and distortion as well as work on thermoelectric response in molecular junctions.Abstract: It is expected that molecular electronics, i.e., the use of molecules as critical functional elements in electronic devices, will lead in the near future to an industrial exploitable novel technology, which will open new routes to high value-added electronic products. However, despite the enormous advances in this field several scientific and technological challenges should be surmounted before molecular electronics can be implemented in the market. Among these challenges are the fabrication of reliable, robust and uniform contacts between molecules and electrodes, the deposition of the second (top) contact electrode, and development of assembly strategies for precise placement of molecular materials within device structures. This review covers advances in nanofabrication techniques used for the assembly of monomolecular films onto conducting or semiconducting substrates as well as recent methods developed for the deposition of the top contact electrode highlighting the advantages and limitations of the several approaches used in the literature. This contribution also aims to define areas of outstanding challenges in the nanofabrication of monomolecular layers sandwiched between two electro...
