MUNICH, Germany, March 11, 2011 — A measurement technique claiming to be 100 times faster than any existing method can measure the dynamics of photoexcited electrons in nanoscale photodetectors using a time-resolved laser spectroscopy process. The new technique allowed Alexander Holleitner and scientists at the Technical University of Munich to measure the precise speed of electrons, which in carbon nanotubes travel about 800 nm in one picosecond. With this measurement setup, scientists can resolve the ultrafast optoelectronic dynamics of carbon nanotubes. A first laser excites electrons in the carbon nanotubes spanning...Read full article

    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.
    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: ...
