Amy Qu recently joined Scienta Omicron as a Test Engineer in Taunusstein, Germany. As a PhD student at the University of British Columbia, Amy has been long time user of Scienta Omicron instrument. She was particularly fortunate to have been involved in the installation and testing process when Prof. Sarah Burke´s group commissioned a combined TESLA JT SPM/ARPES system from Scienta Omicron in 2019.

The Multiprobe prep is the latest addition to Scienta Omicron’s range of modular UHV system platforms. It serves as both a preparation chamber for a wide range of analytical systems, and as an independent UHV system compatible with the addition of the award-winning Variable Temperature SPM (model VT SPM-XA) housed in its own bolt-on chamber.

Graphene Nanoribbons Need to be Protected from Oxygen to Remain Functional

Atomically precise graphene nanoribbons (GNRs) are increasingly being hailed as the potential future of molecular electronics due to the tuneability of their electronic properties, which can be altered via adjusting their length, width, edge structure and the addition of heteroatoms or other doping groups. In their recently published study in ACS Nano, 2021, 15, 3, a team of researchers has used a combination of bond-resolving scanning probe microscopy (BR-SPM), along with theoretical calculations to study (3,1)-chiral graphene nanoribbons [(3,1)-chGNRs] that were synthesized on a Au(111) surface and then exposed to oxidizing environments. All STM experiments were performed using a Scienta Omicron Low Temperature Scanning Tunneling Microscopy (LT-STM), cooled to 4.3 K.
