Research Group Develops Thermo-Photoluminescence for Rapid Imaging and Measurement

Facebook Twitter LinkedIn Email
Today, the most common optical technique for imaging and measurement of thermal conductivity of semiconductors is time-domain thermoreflectance (TDTR), in which a femtosecond pump pulse is used to heat up the sample through a metal film. While widely adopted, the difficulties are well known. Besides the expensive femtosecond lasers, the samples have to be polished to provide a clean, flat surface for a controlled thermal contact with the metal film, so TDTR is invasive and requires careful sample preparation. To overcome these shortcomings, a joint research group from University of...Read full article

    GLOSSARY
    optoelectronics
    A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
