Surface Chemistry on a Polarizable Surface: Coupling of CO with KTaO3(001)

In this work, Ulrike Diebold & Martin Setvin et al. use carbon monoxide to probe whether and how ferroelectric lattice distortions couple to adsorbates. Combined atomic force microscopy/scanning tunneling microscopy (AFM/STM) is used to identify the adsorption configurations of CO, temperature-programmed desorption (TPD) determines the desorption kinetics and energies, and density functional theory (DFT) calculations provide insights into the coupling with ferroelectric lattice distortions. The AFM/STM experiments were performed at T = 4.8 K in an ultrahigh vacuum (UHV) chamber with a base pressure below 2 × 10−9 Pa, equipped with a Scienta Omicron q-Plus LT head and a custom-design cryogenic preamplifier.

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.

Sample Manipulators

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.
