Optoelectronic Materials

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 of interest in the organic and inorganic field of optoelectronic materials over the past 20 years because of significant improvements in material design and purification resulting in dramatic improvements in material performances. Currently, organic materials have received 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. 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 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 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 to be published in this Topic. I cordially invite you to submit feature articles (or review papers) on the Topic “Optoelectronic Materials”. This Topic seeks original contributions focusing on 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.
