Using their novel approach, ULA-SNOM, the researchers managed to reduce the movement of the scanning tip to an incredibly tiny level. In this method, the tip oscillates with an amplitude of only 0.5 ...

Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its ...

High power, high frequency vacuum electronic devices require high brightness, low emittance electron beams to operate [1]. To meet these demands, thermionic cathodes encounter challenges with rapid ...

Some mushrooms are sturdier than others, but it isn’t necessarily because of their chemistry – it’s how the filaments that ...

Photo-induced force microscopy began as a concept in the mind of Kumar Wickramasinghe when he was employed by IBM in the ...

Photon induced near-field electron microscopy has been recently introduced to investigate the dynamics of near-field distributions in nanostructures, with femtosecond time and angstrom spatial ...
