µARPES & Electronic Alignment: Stay Focused, Save Time
New material groups are often inhomogeneous consisting of small flakes or with domain structures on the µm scale. The same scale is relevant for microstructured devices. To extract meaningful high quality ARPES data from such samples requires high spatial resolution in the µm or even nm range. These small spot sizes introduce a new set of experimental challenges.

Real-Space Investigation of the Multiple Halogen Bonds by Ultrahigh-Resolution Scanning Probe Microscopy
The chemical bond is of central interest in chemistry, and it is of significance to study the nature of intermolecular bonds in real-space. In this work, Andrew Thye Shen Wee et al. employ non-contact atomic force microscopy (nc-AFM) and low-temperature scanning tunneling microscopy (LT-STM) to acquire real-space atomic information of molecular clusters, i.e., monomer, dimer, trimer, tetramer, formed on Au(111). LT-STM/nc-AFM measurements were carried out an integrated scanning probe system consists of Scienta Omicron low-temperature scanning tunneling microscopy (LT-STM) combined with non-contact atomic force microscopy (nc-AFM).
Scienta Omicron Newsflyer Spring 2022
Welcome to the Scienta Omicron Newsflyer for Spring 2022 with an opening message from our new CEO Mr. Henrik Bergersen on the importance of filling customer needs and providing values to our customers. The BAR XPS for instance addresses the biggest challenge in APXPS, measuring at industrial relevant pressures. Read more about the BAR XPS break-through results at world record pressures; EVO Compact – the MBE System for 2D material research; new DFS30 analyser with unique electronic alignment capability for µARPES; successful analyser PEAK software upgrade and integration with the control system at SPring-8 synchrotron in Japan; and high resolution qPlus imaging with CO terminated Tip using the INFINITY SPM Lab at the Aix-Marseille University.
Open and Closed Cycle Sample Manipulators
When aiming at high experimental energy resolution for ARPES measurement, it is crucial to achieve ultra-low sample temperatures to quench thermal broadening. This is possible with state-of-the-art cryo manipulators reaching sample temperatures from < 3.5 K and featuring up to 6 fully motorized axes for a large range of movements. The manipulators are available as open and closed cycle. Open cycle manipulators reach lower temperature specifications and are rapidly cooled down from room temperature to 10 K in 15 min. The low He consumption below 1 l/h at ultimate temperature and the possibility to operate with liquid nitrogen at higher temperatures ensure a low operating cost. Closed cycle manipulators have no He consumption providing unlimited holding time.
INFINITY SPM Cooling System Maintenance
Avoid Unplanned Down Time of INFINITY SPM: Preventive Maintenance
We at Scienta Omicron support the research community’s endeavour to increase productivity. Caring for the instruments’ sanity at customer’s laboratories is part of our offering. With virtually unlimited cryogenic operating time our INFINITY SPM is among the leading solutions for high productivity SPMs. Nevertheless, the INFINITY’s cooling system requires special care and maintenance at larger intervals in order to minimize wear and avoid unplanned down time of the system.
