Sub-Angstrom Noninvasive Imaging of Atomic Arrangement in 2D Hybrid Perovskites
In this work, Mykola Telychko, Shayan Edalatmanesh, Kai Leng & Jiong Lu et al. demonstrate a sub-angstrom resolution imaging of both soft organic layers and inorganic framework in a prototypical 2D lead-halide RPP crystal via combined tip-functionalized STM and ncAFM corroborated by theoretical simulations. STM measurements unveil the atomic reconstruction of the inorganic lead-halide lattice and overall twin-domain composition of the RPP crystal, while ncAFM measurements with a CO-tip enable nonperturbative visualization of the cooperative reordering of surface organic cations driven by their hydrogen bonding interactions with the inorganic lattice. The STM and ncAFM experiments were performed under ultrahigh vacuum conditions at 4.4 K using a Scienta Omicron LT STM/AFM System.
Scientists Emulate Nature in Quantum Leap Towards Computers of the Future
A team of quantum computer physicists at UNSW Sydney (Silicon Quantum Computing Lab) led by Professor Michelle Simmons has achieved a major milestone in the race to build the world’s first quantum computer. They have built a quantum processor in silicon to simulate an organic molecule with astounding precision. They described in their recently published Nature paper, how they were able to mimic the structure and energy states of the organic compound polyacetylene – a repeating chain of carbon and hydrogen atoms distinguished by alternating single and double bonds of carbon. They utilize the atomic-precision placement accuracy of the scanning tunnelling microscope (STM) to engineer quantum dots with large on-site energies (U ≈ 25 meV) and uniform size to realize a homogeneous linear array for reliable simulation accuracy.
Scienta Omicron Newsflyer Spring 2022

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.
Scientists Solve the Mystery About the Active Phase in Catalytic Carbon Dioxide Reduction
An international research team led by researchers of Stockholm University has for the first time been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. The results – obtained at DESY´s brilliant light source PETRA III – are published in the scientific journal Science. A better knowledge of the catalytic process of methanol synthesis and the possibility of finding even more efficient materials opens the door for a green transition in the chemical industry.
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. The modular design and the modern network-based application programming interface (API) facilitate integration of additional equipment as well as full integration of the analyser in external control systems.
MATRIX Programming Training
MATRIX offers powerful capabilities with its rich programming interface. Though MATRIX’s functionality is well documented, even experienced programmers may appreciate support to explore the aspects and procedures of the software that are less obvious. This course is intended for people already experienced in using MATRIX with at least basic programming skills who want to take their SPM to new heights.
