Nanowire Probes Provide Visual Enhancement for AFM

Facebook X LinkedIn Email
GAITHERSBURG, Md., May 28, 2014 — Nanowire probe tips originally intended for atomic force microscopes in near-field scanning microwave microscopy (NSMM) applications could have another use. A team from the National Institute of Standards and Technology’s Physical Measurement Lab (PML) has demonstrated that such probe tips, created from gallium nitride (GaN) nanowires coated with titanium and aluminum, could also be used as LEDs that can illuminate tiny sample regions. Optical radiation can excite a sample differently than a microwave signal does during NSMM scanning. This adds a new dimension to the...Read full article

    gallium nitride
    Gallium nitride (GaN) is a compound made up of gallium (Ga) and nitrogen (N). It is a wide-bandgap semiconductor material that exhibits unique electrical and optical properties. Gallium nitride is widely used in the production of various electronic and optoelectronic devices, including light-emitting diodes (LEDs), laser diodes, power electronics, and high-frequency communication devices. Key points about gallium nitride (GaN): Chemical composition: Gallium nitride is a binary compound...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
    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.
