Researchers have demonstrated a unique model that has implications for sensing, imaging, optical communications and memory storage.

Anne L. Fischer

Zinc oxide (ZnO) is frequently used as an alternative to GaN in optoelectronics because of its low cost, ease of manufacturing and wide bandgap. The proliferation of ZnO nanowire devices such as optically pumped lasers, chemical and biological sensors, and field-effect transistors has prompted additional research into the material. A group from the University of California, San Diego, recently looked at the two main factors that contribute to the high photosensitivity of ZnO nanostructures. This image shows p-type ZnO nanowires. Courtesy of the University of California, San Diego. The...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: ...
