Infrared (IR) radiation was first reported 200 years ago by Herschel's experiment with a thermometer, and the first IR bolometer detector was demonstrated in 1880 by Langley using two thin ribbons of platinum foil. Over the years, IR detectors have developed from single-pixel to larger focal plane array, and have become an essential part of many applications in our daily life. However, the further development of IR technology encounters a bottleneck for both photon detectors with traditional semiconductor materials and thermal detectors with thermally sensitive materials. The boost of new materials in the last decades has opened up new pathways for making new IR devices, such as single-atom layer graphene, transition-metal dichalcogenides, black phosphorus, topological Dirac semimetals, with unique characteristics of broadband photon absorption, ultrafast carrier dynamics, and high carrier mobility. The relevant device physics, materials fabrication and characterization technologies, IR imaging systems and applications, are urgent to be researched and resolved.
This Research Topic aims to highlight the latest progress and trends in IR science and technology. The potential topics include IR technologies and applications adopting new concepts, new materials, new structures, and new principles. The readers who are interested in this field will not only see the positive effects brought by the development of these advanced IR materials and technologies but also broaden their knowledge and generate new solutions to surpass the state-of-the-art IR technologies.
The scope of this Research Topic ranges from exploring device mechanisms, developing new materials or processes for making IR devices, to promoting the applications of IR technology. Both Original Research and Review articles are welcome. Potential areas of interest include but are not limited to the following:
• IR Physics
• IR materials
• IR lasers, detectors or modulators
• Applications in the IR spectrum
• IR imaging technology and systems
• Terahertz technology and devices
