Semiconductor Surface States Enhance Wavelength Conversion

Facebook X LinkedIn Email
Electrical engineers from the UCLA Samueli School of Engineering have introduced a solution to enhance wavelength-conversion efficiency by exploring the phenomenon of semiconductor surface states. The work, which establishes a more efficient way of converting light from one wavelength to another, opens doors to improvements in the performance of imaging, sensing, and communication systems. Surface states occur when surface atoms have an insufficient number of other atoms to which they can bind, causing a breakdown in atomic structure. These incomplete chemical bonds, also known as...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: ...
    terahertz
    Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1 and 10 terahertz. One terahertz is equivalent to one trillion hertz, or cycles per second. The terahertz frequency range falls between the microwave and infrared regions of the electromagnetic spectrum. Key points about terahertz include: Frequency range: The terahertz range spans from approximately 0.1 terahertz (100 gigahertz) to 10 terahertz. This corresponds to...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
