A new low-damage imaging technique developed at the Japan Advanced Institute of Science and Technology (JAIST) is opening the door to detailed analysis of fragile nanomaterials for the first time.

The electron scattering rate from a particular point tells microscopists ... It could provide an extra tool in our arsenal to not necessarily completely remove beam damage but certainly to minimize it ...

New light for shaping electron beams Adaptive imaging technique for materials science and structural biology Date: September 29, 2022 Source: University of Vienna Summary: A new technique that ...

2 Cryo-EM has proved a similarly powerful technique in the material sciences, largely for its ability to prevent electron beam damage to very delicate samples. 3 One of the major challenges when ...

These rogue electrons can trigger adverse radiation inside the machine, which may interfere with the electron beam, damage particle accelerator components or infrastructure, or create hot spots ...

A common example is knock-on damage, whereby an intense electron beam can shift the positions of atoms in a sample. “Reducing the electron dose would limit the sample damage, but also the chance to ...

So, the researchers employed new sample preparation techniques, including backfilling the surface with stabilizing molecules to minimize electron beam damage. "We had to convince ourselves—and ...

He shares the results of his electron-beam lithography experiments in his latest video (embedded below). In e-beam lithography, or EBL, shapes are drawn onto a wafer using an electron beam in a ...

By reducing electron exposure by 20 to 500 times compared to conventional methods, the JAIST team achieved high-resolution imaging without the risk of beam-induced damage. Controlling the crystal ...
