Sealable microcells array with ultrathin metal-graphene membrane

A significant challenge in graphene fabrication is the production of large, suspended graphene layers. This issue applies to any kind of graphene-based device and is particularly critical when the fabrication of closed cells is required, for example in the fabrication of large, sealed cells for in-operando XPS or TEM investigation, or the fabrication of Golay cell-like bolometers.

The new laboratory for the cross-beam is ready

The new FNF SEM-FIB laboratory is ready!
The room houses the Leo 1540XB cross-beam, SEM with Gemini column (acc. volt. 0.5-30 KV) and Orsay Physics Ga-ion FIB column. The system, integrated with the Quorum cryo stage (https://fnf.iom.cnr.it/new-cryostage-has-been-installed-cross-beam-fnf-l...), will also allow the investigation of biological samples and polymers, increasing the range of use of SEM and FIB.

New laboratory for the tubolar oven

The spaces of the Nano Fabrication Facility are further enlarged: a new laboratory has been created for the facility, at the MM building, dedicated to tubular furnaces, for the oxidation processes of silicon and for the production of Glassy Carbon.
The maximum temperature of the furnaces is 1200 ° C; the gases available are currently O2, N2 and Ar.
Dry or wet oxidation modes are available for the oxidation of silicon.

A new Cryostage has been installed on the Cross Beam at FNF labs; new possibilities for electron microscopy.

A new Cryostage has been installed on the available Cross Beam at FNF labs; the tool will extend the fields of application of electron microscopy.

It should be noted that a new access mode to FNF will now be possible at a reduced rate, for those interested in accessing only the Dual Beam laboratory; in addition to this, the cryo stage, the sputter coater, the laminar flow hood for sample preparation, and finally the CO2 critical point drier system are also included.

Original design of a patterned multiferroic heterostructure for electrical control of the magnetic shape anisotropy

In the framework of piezoelectric/ferromagnetic patterned heterostructures, the purpose of this work is to electrically control the magnetic properties by tuning the morphology, especially by modifying the magnetic shape anisotropy through patterned strain. We have thus designed and studied a heterostructure with bottom nano-striped and top full film electrodes. ZnO piezoelectric and CoFeB magnetic materials were chosen to respond at critical criteria of its geometry. In addition, numerical simulations and magnetostatic calculations were performed to understand the reproduction of the...

Nanoelectrode Arrays Fabricated by Thermal Nanoimprint Lithography for Biosensing Application

Electrochemical sensors are devices able to determine the concentration, through direct electrical measurements, of molecules and biomolecules in solutions. The miniaturization to a size below the 1 um in small-size arrays of nanoelectrodes (NEA), offers advantages in terms of increased sensitivity and compactness. NEAs of nanoholes on a thin film of polycarbonate (PC) deposited on boron-doped diamond (BDD) macroelectrodes has successfully fabricated by thermal nanoimprint lithography (TNIL), with a high reliability and reproducibility.The device has employed for the detection of, gliadin...

Spatiotemporal superposition of free-electron lasers and laser pulses: integration in a single device.

Time-resolved investigations on any phase of matter through pump-probe methods involving FELs and laser beams is a new frontier for modern science. The underlying problem for these experiments is the requirement of an accurate spatial and temporal superposition of pump and probe beams on the sample: at the present, this is still a critical procedure, also in term of large time needed going to the detriment of the available beamtime.

Computer Generated Holograms using OAM beams: high-security optical elements for anti-counterfeiting applications

A computer-generated holograms (CGH) encoding information for light beams carrying orbital angular momentum (OAM) has been developed in collaboration between IOM-CNR and Padua University. The use of a numerical code, based on an iterative Fourier transform algorithm, allowed a phase-only diffractive optical element (PO-DOE) by exploiting a new method based on transmission through high-order spiral phase plates (SPPs).

Nanostructuring methylammonium lead iodide perovskite by ultrafast nano imprinting lithography

The nanopatterning of the methylammonium lead iodide (MAPbI₃) perovskite, a polycrystalline hybrid organic-inorganic semiconductor with very promising perspectives for photovoltaic and optoelectronic applications has been achieved. Nanopatterning of MAI is obtained via Pulsed-NIL technology, an ultrafast version of the thermal nanoimprint lithography (NIL) based on stamps with integrated heaters. By Pulsed-NIL we were able to replicate onto the hybrid perovskite structures with details at the sub-100 nm scale, in spite of its crystalline nature.

High aspect ratio silicon nanowires control fibroblast adhesion and cytoskeleton organization

Cell-cell and cell-matrix interactions are essential to the survival and proliferation of most cells, and are responsible for triggering a wide range of biochemical pathways. More recently, the biomechanical role of those interactions was highlighted, showing, for instance, that adhesion forces are essential for cytoskeleton organization. Silicon nanowires (Si NWs) with their small size, high aspect ratio and anisotropic mechanical response represent a useful model to investigate the forces involved in the adhesion processes and their role in cellular development.

Contamination-free suspended graphene structures by a Ti-based transfer method

Minimization of contamination associated with the graphene transfer process from the growth substrate to the device surface is a major requirement for large scale CVD graphene device applications. We performed a polymer-free method of commercial CVD-grown graphene transfer from the initial copper substrate to the silicon device: 15 nm-thick titanium layer replaces completely the polymer (PMMA) film as supporting layer during the transfer process. The approach reduces significantly the level of contaminations for supported and suspended graphene layers. Raman spectroscopy proves the...
