Atomic force microscopy (AFM) is a method of topographical measurement, wherein a fine probe is raster scanned over a material, and the minute variation in probe height is interpreted by laser ...

Atomic Force Microscopy (AFM) has evolved into a central technique in nanotechnology, providing three-dimensional imaging and precise measurements at the atomic scale. Its ability to probe surfaces by ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Atomic force microscopy (AFM) and infrared (IR) spectroscopy have emerged as complementary techniques that enable the precise characterisation of materials at the nanoscale. AFM provides ...

Atomic force microscopy (AFM) is a way to investigate the surface features of some materials. It works by “feeling” or “touching” the surface with an extremely small probe. This provides a ...

First invented in 1985 by IBM in Zurich, Atomic Force Microscopy (AFM) is a scanning probe technique for imaging. It involves a nanoscopic tip attached to a microscopic, flexible cantilever, which is ...

Cecilia Van Cauwenberghe explains how to measure the future using nanoscale metrology and discusses the global competition ...

AFM differs significantly from traditional microscopy techniques as it does not project light or electrons on the sample's surface to create its image. Instead, AFM utilizes a sharp probe while ...

Researchers in China have developed an electrical imaging technique using three-dimensional (3D) tomographic conductive atomic force microscopy (TC-AFM) to go beyond indirect characterization of ...

PFM is based on the converse piezoelectric effect, where an applied electric field induces mechanical strain in piezoelectric materials. In PFM, an AC voltage is applied between a conductive atomic ...

Researchers at Oak Ridge National Laboratory have used specialized tools to study materials at the atomic scale and analyze ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...
