Message from Tobias Persson, Vice President, Sales & Services

During the very challenging year with a pandemic affecting all of us, customers, and suppliers as well as our families, adaptation to a new normal has been crucial.

Despite the challenges from the pandemic, Scienta Omicron stayed committed to the scientific community, increasing speed by hiring more staff, ramping production, and investing in the sales and services organisation.

To overcome the international travel restrictions, we have continuously developed methods and offerings of remote training. Thereby we have managed to provide customer training as well as dedicated installation training of our local teams from our headquarters in Europe. A great example of the power of our Global access to Local presence is the achievements made in China throughout 2020. The combination of continuous remote training and support of the skilled local China Team prepared them for installation of entirely new products at the same time as we reduced the overall average installation time with more than 50 %.

Take care and stay safe.

Product Launch: PEAK 

Electron Spectroscopy Control and Acquisition Software

Scienta Omicron is delighted to announce the launch of our latest offering PEAK – Electron Spectroscopy Control and Acquisition Software. PEAK is designed to control acquisition of photoelectron spectra with Scienta Omicron analysers. With its modern software architecture, PEAK offers improved performance for data acquisition, workflow, and live visualisation of data. Watch the video to hear what the experts have to say and get in touch with us for more information at info@scientaomicron.com or contact your local sales representative.

Photodriven Transient Picosecond Top‐Layer Semiconductor to Metal Phase‐Transition in p‐Doped Molybdenum Disulfide

In this work, Nomi L A Sorgenfrei et al. establish how visible light itself can create a transient metallic top layer on bulk crystalline p‐doped 2H‐MoS2. Electron–hole pairs created by optical excitation separate in the surface band bending region of p‐doped semiconducting 2H‐MoS2. This causes a transient accumulation of electrons in the surface region, driving the top‐layer within several picoseconds from the p‐doped semiconducting 2H‐MoS2 into a sheet of metallic 1T‐MoS2 at a remarkably low optical fluence threshold. This mechanism has significant implications on how optically illuminated MoS2 surfaces behave.

Featured Product: HAXPES Lab

A Window to the Bulk

Scienta Omicron's HAXPES Lab brings hard X-ray photoelectron spectroscopy (HAXPES) capability directly to the local laboratory environment. Using world class technology and expert engineering, the HAXPES Lab sets the standard for laboratory based high energy photoelectron spectroscopy. This novel system probes bulk samples properties and accesses deep core level electrons via photoelectron spectroscopy (XPS) without the need for a synchrotron end station.

The Acidity of Individual Atoms - Breakthrough at TU Wien

Researchers at the Institute of Applied Physics at TU Wien can now determine the proton affinity of different surface sites of indium oxide with atomic precision. In a recently published Nature paper, they probed the strength of the hydrogen bonds at the surface sites of indium oxide with the tip of a non-contact atomic force microscope and found quantitative agreement with density functional theory calculations. The experiments were carried out in two different UHV chambers based on a two-vessel system with base pressure of <2x10-10 mbr and <2x10-11 mbr in the preparation and analysis chambers. The analysis chambers are equipped with a Scienta Omicron low-temperature STM/AFM head and a Tribus head respectively, using qPlus sensors and low noise amplifiers.

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.

New Installation: TESLA JT SP System

Department of Physics of the University of Basel, Switzerland

We are very happy to announce that the TESLA JT SPM System installed at the Department of Physics of the University of Basel. Here´s what Prof. Ernst Meyer and his group have to say: "We are delighted to celebrate the final acceptance of the newly installed TESLA JT SPM system developed by Scienta Omicron at the University of Basel. This low temperature (1K) STM/AFM microscopes equipped with an external magnetic field of 3T will be used to characterize structure, electronic and magnetic properties of quantum materials, nanographene and superconductors down to the atomic scale."
