Vienna Node

The Vienna node combines in the OVID laboratory three development platforms implemented at the Faculty of physics in the group electronic properties of materials:

DOM

This platform deals with the development of optical methods (DOM) in micro/nano spectroscopy and focuses on combined application of multifrequency Resonance Raman, UVVis, Infrared and photoluminescence microscopy. We also developed a new ultra-stable flexible platform enabling the fast exchange between different in-situ setups for doping experiments as well as microscopy optical cryostats (one LHe flow cryostat, one vibrational decoupled closed cycle cryostats and several LN2 cryostats).

PORTES

This platform deals with the development of novel ultra-high vacuum (UHV) sample transfer systems enabling the combination, transport, x-ray photoemission (XPS) and angle resolved photoemission spectroscopy (AR)PES with optical methods (micro Raman, IR and UVVis) in one system.
This involves one 6 axis rotational LHe cryomanipulator and the combination of several preparation and transfer chambers in one purpose built UHV setup. For this platform we combined a Bruker and FTIR 80V, a Horiba LabRam, and a Scienta-Omicron, hemispherical high resolution (AR)PES electron analyser and a high power Gammadata lamp.

MORE-TEM

MOmentum and position REsolved mapping Transmission Electron energy loss Microscope funded by an ERC-synergy project - a revolutionary scientific instrument for materials science: In MORE-TEM, we develop a new spectrometer enabling to map excitations q-resolved with 0.01 Å-1 resolution and q-averaged down to atomic level, at unprecedented 1 meV energy resolution and at variable temperature between 700K & 4K. This opens the so-far unexplored possibility to investigate dispersion and lifetime of phonons, plasmons & excitons in nanomaterials including (organic) molecules, 1D nanotubes, 2D materials, heterostructures & nanocrystals in minerals with a few nm of lateral resolution on samples as thin as an atomic monolayer. Mapping out the spatial and q-landscape of primary excitations will allow us to gain control on quantum phases, like charge-density waves and superconductivity, to engineer new materials for energy (e.g. batteries), (opto-electronic devices in (organic) electronics, and to model the physical and chemical properties of natural geological systems. This will hugely impact a wide range of applications in physics, chemistry, engineering, as well as in environmental-, geo- & material science. MORE-TEM not only implements features of a large-scale facility on a cheaper table-top instrument, but it also pushes q-resolved spectroscopy to the realm of the nanoscale, providing thus a fundamentally new & unique infrastructure for the characterization and optimization of nanomaterials.

Osaka node

The Osaka node combines in the OVID laboratory two major projects implemented at the Department of Nanocharacterization for Nanostructues and Functions at the SANKEN institute:

Triple C

In the Triple C project we are developing the dedicated low voltage TEM/STEMs for high-sensitivity analysis with the supports of Japanese funding agency (JST-CREST). Triple C2 is a unique high-energy resolution TEM with the floating monochromator which allows us the high resolution TEM and high-resolution EELS on low dimensional materials. Triple C3 is a dedicated STEM with a delta-type aberration corrector which enables us single atom spectroscopy.

OASP

In the Osaka Advanced Specimen Preparation (OASP) project we develop new tools in material design of freestanding high purity hybrid low dimensional materials as specimen for TEM. This involves projects which will realize the combination of different low D materials via direct synthesis, transfer and subsequent cleaning. The materials involved range from nanotubes, mono-atomic layers, individual molecules and their composites as well as heterostructures.
