1.3-nm Photodetector Can Generate More Current Than Thicker Devices

Facebook X LinkedIn Email
A photodetector that is ten times smaller than current standard silicon diodes has been developed using molybdenum disulfide (MoS2) sandwiched between two graphene sheets. The 2D device, which has just one layer of MoS2, demonstrated the ability to produce more photocurrent than comparable multilayered devices, even though it absorbed less light. To discover the reason for this surprising result, researchers from the Institute of Basic Science (IBS) compared photovoltaic devices with one layer of MoS2 with devices with seven layers of MoS2, and tested how well the devices were able to...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:...
