Angle-Resolved Photoelectron Spectroscopy (ARPES) has emerged as the most powerful technique to understand the electronic structure of materials and what can influence their physics and chemistry. The ARPES Lab is designed to maximise the advantages gained from the revolutionary DA30-L hemispherical high-resolution analyser with its patented in-lens deflector. The analyser measures the full 3D surface cone of a band-structure without sample tilt.
Revealing the band-structure of the valence band and the Fermi-level is fundamental to understanding electron transport, band-gap phenomena and spin-related effects. The progress of new technologies and the development of emergent materials rely more than ever on the ARPES technique to provide a precise understanding of the inherent abilities of complex material systems. This powerful tool is now being extended to time-resolved ARPES experiments yielding direct dynamical information during the evolution of electronic band structure.
Scienta Omicron, the provider of the world leading electron spectrometers to specialist in the field, also offers complete turn-key automated ARPES measurement systems with guaranteed performance and expert local support as part of our “Materials Innovation Platform (MIP)”.
The Scienta Omicron ARPES Lab performs band structure mapping measurements faster, more precisely, yielding data sets with fewer variables for simplified data analysis than any other system available. Magnetically shielded chambers and cryogenic sample manipulators that are the standard for many advanced synchrotron endstations are the building blocks to the Scienta Omicron ARPES Lab.
Intelligently integrated with superior automatisation and software control from data acquisition reaching through vacuum control, the ARPES Lab brings the powerful ARPES technique into an accessible and reliable measurement tool. A pumping system optimised to lowest working pressures even when operating with He-discharge lamps extends sample lifetime and integrity.
Best Technology Concept
The ARPES Lab is designed to maximise the advantages gained from the revolutionary DA30-L hemispherical high-resolution analyser with its patented in-lens deflector. The analyser measures the full 3D surface cone of a band-structure without sample tilt by deflecting the electron trajectories perpendicular to the analyser entrance slit, which allows for:
- Improved ky accuracy in shorter measurement times
- Maintains near constant matrix elements by keeping sample angle fixed
- Ensures reliable measurement position on a fixed sample point necessary for exploring dichroic effects in ARPES and measuring very small samples and/or multi-domain samples
For wide range Brillouin zone scans the motorised sample manipulator is integrated into the measurement (SES) and system software (MISTRAL). The software driven adjustment of the manipulator allows for:
- Precise sample movement during scans
- Automatic movement of the sample between different measurement positions (ARPES, LEED, etc.)
- Security interlocks for manipulator movement
All manipulators (4, 5, or 6 axis) are available in a very low temperature version (< 6 K) to allow for high energy resolution.
Experts in magnetic shielding design have perfected the chamber to achieve the highest performance from the combination of analyser and excitation sources. The ARPES Lab can support multiple light sources covering a broad energy range to enable investigation of all class of materials. The renown VUV5k high intensity monochromatic light source can be paired with new laser sources providing selectable energies and polarization exhibiting extremely narrow line width and/or ultra-fast pulse width for time resolved ARPES. The ARPES Lab can additionally support a monochromatic X-ray source for core level chemical state analysis.
Designs incorporating the latest techniques are available; additionally Scienta Omicron can custom tailor the system to enable your unique ideas.
