Research highlights | Publications![]() Atomically-Precise Texturing of Hexagonal Boron Nitride Nanostripes
h-BN grown on a curved Rh crystal forms a continuous atomically-thin carpet revealing a transformation from 2D to 1D electronic band structure. This novel approach to nanopattering through epitaxial growth has practical technological implications.
![]() Boron nitride-graphene in-plane hexagonal heterostructure in oxygen environmentInsights into the progressive and subsequent intercalation of oxygen, selective etching of graphene and oxidation of boron in a quasi-free standing Gr-h-BN monolayer during oxygen exposure. ![]() Improving the Efficiency of Gallium Telluride through Defects Engineering and Interfacing with its Native OxideThe formation of a nanoscale sub-stoichiometric wide-band-gap Ga2O3 skin over narrow-band-gap gallium telluride upon air exposure is beneficial for electrocatalysis, photocatalysis, and gas sensing. ![]() Soft x-rays spectroscopies in liquids at BACHWe have developed suitable cells to perform soft x-ray spectroscopy in the presence of liquids and reagent gases at ambient pressure: two types of static cells working in transmission or in fluorescence modes, and an electrochemical flow cell which allows to carry out cyclic voltammetry in situ, electrochemical deposition on a working electrode and to study chemical reactions in-operando conditions.

Transition-metal dichalcogenides hosting topological states have potential implications for catalysis and nanoelectronics. The chemical reactivity and ambient stability of NiTe2 has been investigated in order to assess the suitability of technology transfer. ![]() Under-cover stabilization and reactivity of a dense carbon monoxide layer on Pt(111)
A densely-packed CO overlayer on Pt(111) has been stabilised under a 2D cover formed by a h-BN–graphene in-plane heterostructure. The 2D layer influences the CO–Pt bond and CO reacts with the h–BNG cover at an elevated temperature at the h-BN–graphene boundaries. ![]() Temperature-Programmed Photoemission @ BACH
Temperature-programmed (TP) photoemission spectroscopy (core levels, ARPES, work function) can be performed at BACH with controlledtemperatureramp thanks to a PID controller and a quick acquisition mode. ![]() Tailored boron‑nitrogen‑carbon 2D layers
The chemical composition and interaction strenght with the substrate of a 2D layer composed of C, B and N has been tuned by growing the heterostructure on different polycrystalline metals (Pt, Ni, Fe) at different temperatures. The layer grown on Pt has been transferred on a SiO2/Si substrate by a simple electrolytic delamination. S. Nappini et al. Applied Surface Science (2019), DOI: 10.1016/j.apsusc.2019.01.274.

MultiSpectroscopy endstation
In the UHV (low 10-10 mbar) endstation of the BRANCH A it is possible to perform a multi-spectroscopy investigation with photoemission UPS/XPS (including polarization and photon energy-dependent ultra-violet (UV) and soft-x SX-ARPES, RESPES and energy-dependent Photoelectron DIffraction PhD, temperature-progarmmed photoemission TP-XPS), x-ray absorption XAS (TEY,PEY,TFY,PFY) including GAP SCAN acquisitions, x-ray emission XES and x-ray magnetic circular dichroism XMCD (in remanence in the branch A). A LEED and several electron beam evaporators are available to deposit selected metals on the sample surface at different temperatures. A sample-preparation UHV chamber, directly connected to the EndstationA can be used to grow thin films of metals or metal oxides and deposit organic/inorganic molecules on solid surfaces for in-situ investigations. High-partial pressure gas exposures (up to 100 torr) and sample annealing are also possible in a dedicated chamber. Connection of vacuum suitcases is also feasible. Samples in static liquid environment can also be measured in fluorescence yield. |

ComIXS fluorescence spectrometerThe fluorescence spectrometer ComIXS (Compact Inelastic X-ray Spectrometer) installed at the BRANCH A is devoted to the energy analysis of the photons emitted from the sample in the experimental chamber (under synchrotron radiation) for RIXS (resonant x-ray emission spectroscopy) and XES (x-ray emission spectroscopy). It takes advantage of two variable line spacing spherical gratings to cover the range from 20 (35) eV to 1200 eV with high efficiency, but limited resolution (resolving power around 800-1000). The data acquisition is made by a back-illuminated peltier-cooled CCD camera optimized on the soft x-ray energy range. Please contact us if you are interested (the instrument is not currently available to users).Cells for measurements in liquid environment (NEW)Cells for fluorescence yield XAS measurements in static liquid environment are available also for users. Other cells are under development.Please contact us if you are interested. Branchline C
A third BRANCH C is also available for the installation of user endstations for long term projects. |

User Area
Proposal Submission
Before submitting a proposal for the BACH beamline we invite user to read the Info for Users and this page to have an updated information on the endstations and instrumentation. In any case we invite users and collaborators to discuss their proposals with the beamline local contacts well in advance before the submission deadline. This is crucial for a careful assessment of the experiment feasibility and may lead to improvements in the proposed experimental plan. We invite users interested in installing a bulky piece of equipment (such as an entire experimental station) which takes a long time to assemble and dismount to discuss their project with the beamline local contacts well in advance before the submission deadline.
Next call:VUO-Elettra: March 2023for proposals eligible for the user period starting from July 1st to December 31th, 2022.
