Nature features Electron-Beam Manipulation of Silicon Dopants in Graphene

03.12.2018

The work of Toma Susi and colleagues on atom manipulation is gaining international recognition in the recent News Feature on advances in electron microscopy 'The microscope revolution that's sweeping through materials science' in the scientific journal Nature.

Toma Susi (Physics of Nanostructured Materials) was interviewed for the recent feature “The microscope revolution that’s sweeping through materials science - Technological advances are transforming what researchers can study at the atomic scale” in the journal Nature. The work of Dr. Susi and his colleagues highlighted in the feature is based on the article “Electron-Beam Manipulation of Silicon Dopants in Graphene” which was published in Nano Letters in June 2018. The web version of the feature includes an animation by Dr. Susi showing how a silicon impurity is moved around inside a hexagonal graphene lattice using the focused electron beam of a scanning transmission electron microscope.

A silicon impurity is moved around inside a hexagonal graphene lattice using the focused electron beam of a scanning transmission electron microscope. Atoms could be manipulated at the rate of around four jumps per minute. (© Tripathi, M. et al. Nano Lett. 18, 5319–5323 (2018). CC BY.)
