Electron and optoelectronic applications

Electronic and Optoelectronic Applications of TeUurides. Most metal teUurides are semiconductors with a large range of energy gaps and can be used in a variety of electrical and optoelectronic devices. AUoys of the form HgCdTe and PbSnTe have been used as infrared detectors and CdTe has been employed as a gamma ray detector and is also a promising candidate material for a thin-fUm solar ceU. 

Another evaporation technique is molecular beam epitaxy (MBE). MBE produces extremely pure and very thin films with abrupt composition changes and is being considered for extremely exacting electronic and optoelectronic applications. PI However, the deposition rate is very slow and the process is still considered experimental. 

Since 2004 [183], graphene research has evolved from a heavily theoretical and fundamental field into a variety of research areas [301]. Its electrical, magnetic, physical-mechanical, and chemical properties position it as the most promising material for molecular electronic and optoelectronic applications, possibly replacing the currently used silicon and metal oxide based devices. Nonetheless, further research is essential in order to control easily such properties and construct devices with specific and novel architectures to explore in depth all of these exciting properties, as well as to achieve the synthesis of large-scale, size- and layer-count controlled graphene. 

Nitrides are used for their high strength and hardness, in nudeai applications, solid electrolytes, refractories, abrasives, coatings and lubrication, catalysis, and electronic and optoelectronic applications. 

Owing to the intrinsic optical and photophysical features discussed for metallopolyynes, it is expected that they have great potential as active materials in optical and photonic devices. Over the years, numerous studies have shown that these metallopolymers can be exploited for a collection of electronic and optoelectronic applications. 

In addition to the numerous electronic and optoelectronic applications mentioned above, novel applications of CVD are also being used to generate macroscopic components (10 cm as opposed to 1 nm). One interesting example is the production of Ir/Re thrust chambers for liquid rocket motors (see Figure 6). For this structure... 

Metal pnictides are best represented by the 13-15 compounds (e.g., GaAs), which are well known for their electronic and optoelectronic applications. Molecular precursor approach to the preparation of these materials has been investigated and reviewed by Maury and Cowley,who have also actively contributed to the field. 

An epoch of using organic materials for electrical, electronic, and optoelectronic applications has been going on since 1977, when Chiang et al. [1] discovered a tremendous increase of 11 orders of magnitude in electrical conductivity of polymer when halogen was introduced into polyacetylene. A new nomenclature of "organic semiconductors" was therefore coined... 

Thus, fluorinated polyimides are an attractive class of materials for various applications such as in high-performance structural resins, coatings and films that are thermally stable, gas separation membranes, optical waveguides, and other electronic and optoelectronic applications [39-41]. 

Nanotechnology is deeply embedded in advanced devices for electronic and optoelectronic applications. 

Two more examples of coordination polymers have recently been introduced by this group applying Co + and Ga metal ions in a porphyrin framework analogous to the dimer 11. hi both examples the porphyrin units are strongly aggregated which makes these systems potentially interesting for electronic and optoelectronic applications [ 13,76]. 

As more varieties and grades of thermotropic LCPs become available worldwide, and as more confidence is gained in the cost-effective utilization of LCPs, more applications will be developed. Thermotropic LCPs are indeed special polymers for electronic and optoelectronic applications.
