Equipment<\/strong> “Laboratorio de F\u00edsica de Superficies e Interfaces”<\/strong><\/h3>\n\n\n\n

Scanning tunneling microscope (STM-UHV)<\/strong><\/p>\n\n\n\n

\"P1010166\"<\/strong><\/p>\n\n\n\n

STM is used to study and develop new micro and nanostructured materials. It can characterize surfaces, from the acquisition of images at atomic scales. It works under ultra-high vacuum (UHV) conditions. It is used to analyze samples sensitive to environmental conditions with a low vapor pressure at room temperature.<\/p>\n\n\n\n

Scanning Probe Microscope (SPM)<\/strong><\/p>\n\n\n\n

\"103_1811b\"<\/p>\n\n\n\n

SPM allows working with several techniques, all of them under atmospheric conditions: Scanning Tunneling Microscopy (STM), Atomic Force Microscopy (AFM), Kelvin Probe Force Microscopy (KPFM), and Magnetic Force Microscopy (MFM). In particular, the most popular of these techniques, Atomic Force Microscopy, has great versatility and simplicity, being used for the topographic characterization of surfaces due to its high-resolution power, especially when measuring heights in Z, allowing the study of mechanical, electrical and magnetic properties of materials.<\/p>\n\n\n\n

Low-energy ion time-of-flight spectrometer (LEIS-TOF)<\/strong><\/p>\n\n\n\n

\"P1010165\"<\/p>\n\n\n\n

This instrument measures the energy of ions and neutral atoms scattered on the surface of a material using the time-of-flight technique. The ion gun used can generate ions between 1 and 10 keV from a wide variety of gases, liquids, or solids. The technique has a very good depth resolution (first atomic layers of the surface). The possibility of detecting charged and neutral particles independently allows basic studies of charge transfer between an ion and a surface. The equipment has an electron gun to implement the low energy electron diffraction technique (LEED), and Auger electron spectrometry (AES).<\/p>\n\n\n\n

Multi-technique surface spectrometer<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

This instrument is designed to perform surface chemical analysis by various techniques under ultra-high vacuum conditions: photoelectron spectroscopy with X-ray (XPS) and ultraviolet photon sources (UPS), spectroscopy of ions originating from ionization of the material (SIMS) or secondary ions, as well as scattered ions (ISS) from an ion source. The characteristics of the sample holder allow the implementation of angular resolution techniques (ARPES).<\/p>\n\n\n\n

Auger Electron Spectrometer (AES)<\/strong><\/p>\n\n\n\n

\"P1010169\"<\/p>\n\n\n\n

Auger electron spectrometry is used to determine the elemental chemical composition of surfaces, in a few nanometers of thickness. A surface erosion process, by ion bombardment, allows controlling the composition of the material in depth. Other possible techniques are the detection of secondary electrons of lower energies of the emission spectrum (SEE), which allows the study of chemical changes, and incident low-energy electrons scattered in the material (EELS), which provides information on the atomic energy levels of the sample.<\/p>\n\n\n\n

High Performance Computing cluster PIRAYU Santa Fe Argentina<\/strong><\/p>\n\n\n\n

In December 2016, the cluster was inaugurated with 31 nodes (1 server, 1 NAS, 25 compute nodes, 5 nodes with GPU, and 1 node with Xeon Phi), providing an initial capacity of 22 TFlops. In November 2017, an additional 2 compute nodes of 24 cores and 128 GB RAM were purchased. The configuration was upgraded in June 2017 and the computational capacity was increased to 27 TFlops thanks to 5 new 24-core nodes.<\/p>\n\n\n\n

The name Piray\u00fa is given by the native peoples to one of the characteristic creatures of the Argentine coastal fauna: the dorado (Salminus brasiliensis). This muscular fish is known for its speed and power, something that inspired the members of the consortium to choose a name for what would be the most powerful supercomputer (so far) in the region.

This project represents one of 17 productive innovation projects and highly complex equipment that was selected in the first call for proposals of the Santa Fe Science, Technology and Innovation Agency (ASACTEI).<\/p>\n\n\n\n
