Message from our New Chief Service Officer (CSO) Dr. Susanna Eriksson
Welcome to our Newsletter for November 2021.
This is very special month and year for Scienta Omicron! 40 years ago – in 1981 Prof. Kai Siegbahn was awarded with the Nobel Prize in Physics for developing the method of Electron Spectroscopy for chemical analysis (ESCA/XPS) – thereby creating the starting point for Scienta. Since then, the company has expanded and its product portfolio has been extended to incorporate Molecular Beam Epitaxy, Thin Film Deposition, Scanning Probe Microscopy Systems and a wide range of components.
The last four decades have been an exciting, inspiring and innovative journey and Scienta Omicron would not be where it is today without all of you our collaborators, partners, customers and above all the fantastic colleagues and team members. Your contributions and support are invaluable. We are supremely grateful to all of you – A BIG THANK YOU!
We look forward to be with you in future too with all our challenges and your successes; enabling you in your ground-breaking research with our cutting-edge and state-of-the-art instrumentation.
The new DFS30 analyser features ground-breaking Electrostatic 3D Focus Adjustment technology - a major advancement in replacing imprecise mechanical movements with electronic precision and repeatability. This provides significantly improved workflow, speed, and reproducibility when optimizing experimental conditions. High quality ARPES measurements, particularly μARPES and nanoARPES, require optimised alignment of the photon source, sample, and analyser focal point. The DFS30 simplifies this with electronic adjustment of the analyser focal point.
System Solutions Configured Specifically for Your Research
We are excited and proud to launch CREATE, Scienta Omicron´s new configurable platform for UHV system design. The CREATE platform combines the modules of a proven design solution to form an advanced UHV research system solution with guaranteed specifications. Designing a system using the CREATE platform with your Scienta Omicron expert provides clear decision pathways for capabilities and specifications. By developing and deploying this next generation platform, Scienta Omicron increases the overall capacity for delivering both made-to-order and CREATE platform systems to customers around the world.

Role of Alkali Cations in Stabilizing Mixed-Cation Perovskites to Thermal Stress and Moisture Conditions
In this work, Suresh Maniyarasu, Andrew G Thomas, Wendy R Flavell, Ben F Spencer et al. investigate the chemical composition of two different mixed-cation perovskite compositions using laboratory based Ga Kα (9.25 keV) HAXPES. Chemical composition over 45 nm of sampling depth was quantified using angle-dependent HAXPES measurements. This technique allows more accurate quantification of the alkali metal-cation distribution than is possible using conventional XPS. The elemental distribution and bulk composition of the multiple-cation perovskite materials were studied through angle-dependent HAXPES measurements with a constant energy X-ray source. The high-throughput HAXPES Lab (Scienta Omicron) is located in the Henry Royce Institute, University of Manchester.
Scientists of the University of Graz succeeded in visualising the electronic structure of long-chain organic semiconductors and altering it by means of temperature effects in a controlled manner. More specifically, they demonstrated that monolayers of heptacene on Cu(110) behave markedly different compared to all previously studied oligoacene monolayers on coinage metal surfaces and are dissimilar to any other polycyclic aromatic hydrocarbons adsorbed on metal substrates studied so far. Photoemission tomography measurements were performed using the NanoESCA system and the STM and LEED measurements were performed in a two-chamber system with a variable-temperature Scanning Tunnelling Microscopy (VT STM) both from Scienta Omicron.
An Integrated Quantum Material Testbed with Multi-Resolution Photoemission Spectroscopy
In this Review of Scientific Instruments 92 (2021), Chenhui Yan, Emanuel Green, Riku Fukumori et al. present a new integrated platform for synthesis and characterization of novel quantum material devices. The MBE growth chamber, which has a base pressure of 3 × 10−10 mbar, is connected under ultrahigh vacuum (UHV) to a multi-resolution photoemission spectroscopy (MRPES) setup. This MRPES setup integrates a ECR based helium lamp, a narrow bandwidth 6 eV laser, and a tunable ultrafast laser, which effectively combines static ARPES, trARPES, and μARPES. This setup provides a first-time all-in-one solution for multi-modal photoemission spectroscopy. The setup includes a Scienta Omicron Lab10 MBE for material synthesis and a ARPES Lab for characterization equipped with a VUV5k helium ECR lamp and a DA30-L hemispherical electron analyzer.
Exchange Your old ISE10 Sputter Gun with a new FDG15 Sputter Source and Controller
Every successful story comes to an end! The ISE10 ion sputter source, which has been used by many customers for almost 20 years, is no exception. Since all spare parts are no longer available, we are no longer able to service all repair orders. Therefore, we are pleased to offer the FDG15 as a replacement for the ISE10 for a special price. The FDG15 is our recommended replacement for your ISE10 and the perfect solution for sample cleaning and basic depth profiling. Its Gaussian ion beam produces a variable spot size from 300 µm up to 10 mm. Differential pumping is possible, but not mandatory.
Do you have advanced degree in Physics or Engineering, experience in experimental surface analysis and UHV technique, and design experience in vacuum system construction or mechanical design? Scienta Omicron is currently looking for a new team member as a Project Executive (m/f/d) to support for sales and product management on special technical issues, among others. Start into a future with the best development opportunities and the security of a globally active group of companies.
