Optoelectronic Materials, 2nd Volume

Dear Colleagues,

Optoelectronic materials have been developed for almost a century since studies of their optical and electronic properties were first reported in the 1910s. In the 1960s and 1970s, interest in optoelectronic materials was intensified because of the discovery of electroluminescence in conducting polymers and molecular crystals. Moreover, there has been a real surge in interest in the organic and inorganic field of these materials over the past 20 years because of significant improvements in material design and purification, which resulted in dramatic improvements in material performance. Currently, optoelectronic materials are receiving extensive attention for their applications in electronic and optoelectronic devices, such as light-emitting diodes (LEDs or OLEDs), photorefractive (PR) devices, sensors, solar cells, thin-film transistors, etc. Of particular technological interest are low-cost solution-processed thin films that can be deposited on large areas and/or flexible substrates. Understanding the physical–chemical properties of these materials is crucial in the development of high-performance optoelectronic devices. The goals of this Topic are to provide a balanced assessment of the current understanding of the physical mechanisms that determine the optoelectronic properties of high-performance organic–inorganic materials, highlight the capabilities of various experimental techniques to characterize these materials, summarize the most important in-line device performance, and outline recent trends in the further development of the field. This Topic focuses on photoinduced processes and electronic properties for optoelectronic applications that rely on charge carrier photogeneration. Electronic applications (e.g., OFETs or spintronic devices) and optoelectronic applications (e.g., OLEDs) that do not rely on photogenerated charge generation, as well as photonic applications (e.g., exciton–photon coupling in microcavities), are also welcome in this Topic. We invite you to submit feature articles (or review papers) on the Topic “Optoelectronic Materials”. We are seeking original contributions focusing on, but not limited to, the following (or related) subtopics:

• Charge transport mechanisms in optoelectronic materials;
• Synthesis of organic and inorganic materials for optoelectronic applications;
• Theoretical and experimental methods in optoelectronic materials;
• High-mobility conjugated polymers;
• Photonic and electronic processes and interfacial phenomena in organic–inorganic hybrid materials;
• Emerging materials for optoelectronics;
• New insights of optical materials for optoelectronic applications;
• New photonic concepts to enhance the efficiency of optoelectronic materials;
• Heterogeneous integration of material on silicon platform.
