Atomic point contact significantly enhances Raman scattering

Atomic point contact significantly enhances Raman scattering 2 New research shows that allowing the atomic point of a tip-enhanced Raman spectrometer to touch the surface of a sample increases sensitivity. Researchers have discovered a huge enhancement of Raman scattering mediated by the formation of an atomic point contact between a plasmonic silver tip and a Si(111)-7×7 reconstructed surface. This state-of-the-art low-temperature tip-enhanced Raman spectroscopy (TERS) allows scientists to conduct atomic-scale vibrational spectroscopy. The developers suggest this technique could pave the way for exploring atomic-scale light-matter interactions, leading to a new discipline in light science and technology. According to researchers, the rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy to characterise its atomic-scale structures and defects in detail. TERS has demonstrated the exceptional sensitivity required to observe vibrational

Atomic Point Contact Considerably Enhances Raman Scattering at Nanoscale

Atomic Point Contact Considerably Enhances Raman Scattering at Nanoscale Today, nanofabrication of electronic systems has reached a 1 nm scale (10 − 9 m). The quick development of nanotechnology and nanoscience currently needs atomic-scale optical spectroscopy to define atomistic structures that will influence the functions and properties of the electronic devices.

Image Credit: National Institutes of Natural Sciences. The international research team, led by Takashi Kumagai from the Institute for Molecular Science, observed a massive improvement of Raman scattering facilitated by the development of an atomic point contact between a Si(111)-7×7 reconstructed surface and a plasmonic silver tip. This was realized using advanced low-temperature tip-enhanced Raman spectroscopy that hel

Nanotechnology Now - Press Release: 3D design leads to first stable and strong self-assembling 1D nanographene wires

Home > Press > 3D design leads to first stable and strong self-assembling 1D nanographene wires Schematic illustration of hierarchical structures of carbon nanofiber bundles made of bitten warped nanographene molecules. CREDIT NINS/IMS Abstract: Nanographene is flexible, yet stronger than steel. With unique physical and electronic properties, the material consists of carbon molecules only one atom thick arranged in a honeycomb shape. Still early in technological development, current fabrication methods require the addition of substituents to obtain a uniform material. Additive-free methods result in flimsy, breakable fibers until now. 3D design leads to first stable and strong self-assembling 1D nanographene wires Tokyo, Japan | Posted on April 6th, 2021
