UV Light Used to Characterize Devices, Improve Performance

Facebook X LinkedIn Email
NAGOYA, Japan, June 13, 2019 — Researchers from the Nagoya Institute of Technology (NITech) used UV light to test the performance of miniaturized semiconductors for next-generation electronics. Specifically, the team determined the interface properties of a graphene-gallium nitride (GaN) heterojunction device by characterizing the device under UV illumination. According to the team, an understanding of GaN heterojunction device interfaces and how to improve them is necessary for better device performance. The researchers demonstrated the effect of UV illumination on electrical hysteresis — a phenomenon in which...Read full article

    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
    graphene
    Graphene is a two-dimensional allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice pattern. It is the basic building block of other carbon-based materials such as graphite, carbon nanotubes, and fullerenes (e.g., buckyballs). Graphene has garnered significant attention due to its remarkable properties, making it one of the most studied materials in the field of nanotechnology. Key properties of graphene include: Two-dimensional structure:...
