Explore the mechanisms of materials
Sony has developed electronics products and devices through R&D on a wide variety of materials. We are currently focusing on technology that provides new functions by taking advantage of our nanometer-scale design capabilities in research on new materials. An example is graphene, a currently popular nanocarbon material. Utilizing the remarkable properties unique to graphene, we are exploring the possibilities of new devices which have never existed in the world before. By accumulating technologies such as materials synthesis, microstructure formation, device fabrication and nanometer-scale material design, as well as putting them to use in devices, we are creating the future.
Sony conducts research and development on various functional materials/ devices and products, utilizing material analysis technology and reliability analysis technology with a scientific approach. We are also developing the advanced analysis techniques required for the research and development. Furthermore, we are developing simulation technologies from the atomic/ molecular level, from first principles calculations to macro-level simulations such as stress, fluid, and wave optics. These simulation technologies enable understanding and prediction of various phenomena on a multiscale basis. Through these activities, we are blazing trails worldwide with our products.
The science of materials informatics involves changing materials and device development methodologies dramatically by combining mathematical and information science such as AI and machine learning, while searching for new materials, alternative materials, and new device structures efficiently. Sony regards materials informatics as being an essential tool for materials and device R&D, and is currently searching for new functional materials, optimal device structures, and device process conditions using advanced mathematical techniques.
Semiconductor lasers are expected to be applied in a wide range of fields, such as displays, optical communications, sensing, laser processing and medical applications. We are developing lasers with wavelengths from ultraviolet, visible light to infrared, and output power from the mW to the W level. Vertical-Cavity Surface-Emitting Laser (VCSEL), which are suitable for miniaturization and reducing power consumption, are under development not only in the infrared range, but also in the visible range. Our high power nitride-based edge-emitting lasers and VCSELs with originally-designed structures have showed world-class performance, garnering significant attention and earning strong recognition at domestic and overseas academic conferences. Our next target is to widen the wavelength and output power range in order to pursue more applications.
We are developing full-color laser rewritable technology to make it possible to change product designs and colors according to each customer’s preferences and interests, which changes the way everything is done. This technology for non-contact drawing and erasing with laser irradiation uses photoconversion agents which convert laser light into heat on developers and leuco dye that has cyan, magenta and yellow colors, causing color changes that deliver vivid full coloration.
