The newly established Advanced Material Facility is a core service facility at the NANOTEC-Lecce Institute, which provides researchers access to the state-of-the-art systems for the realization of metal, dielectric and semiconductor thin films. Specific objectives include: (1) studies and preparation of high quality epitaxial or polycrystalline films and mesoscopic structures; (2) providing scientific and technical training on material synthesis; (3) supplying technical assistance and consultation for specialized thin films applications; (4) enabling academic or industrial research groups to access novel materials and technologies on a collaborative or commercial basis.
The Nanofabrication Facility the CNR NANOTEC@Lecce is a wide area clean room (class 100-10000), supported by dedicated staff, and equipped with world-class capabilities in the areas of optical and electron beam lithography and micro/nano patterning. In strong synergy with the Advanced Material Facility, a large number of materials can be processed by performing a variety of micro and nanofabrication approaches in order to enable new functionalities in materials, devices and nanostructures. In addition, the Facility is devoted to provide scientific and technical training on micro and nanofabrication tools, and to enable academic or industrial research groups to access novel technologies on a collaborative or commercial basis.
In the facility state of the art equipment for realization and characterization of organic and hybrid optoelectronic devices and the related physic processes. In the facility a cluster tool of five evaporation chambers is available operating in high vacuum up to 10-8mbar, arranged around a central distribution chamber. A mechanical arm allows to transfer the samples in the different chambers under vacuum. In details, the camber is dedicated to the deposition of metal oxides with sputtering and e-beam techniques, thermal evaporation of organic semiconductors and metals and the electro-optical characterization. This system allows the growth of multilayered and doped organic devices by means of nine evaporation sources for organic materials under vacuum. In addition, adjoined glove-boxes equipped with a thermal evaporator, spin-coater, device testing rig and other tools for the sysntesis of colloidal nanocrystals and hybrid perovskite and hybrid and organic material processing for electroluminescent and photovoltaic device fabrication and testing in fully inert atmosphere. The optical simulation for device cavity and device encapsulation are carried out routinely. Other deposition techniques, such as spray-coating, and tools for optoelectronic and photophysical characterization of materials and devices are available (solar simulator, IPCE, Kelvin probe, electroluminescence efficiency, ….) various techniques to study charge carrier concentration, mobility, conductivity, trapping phenomena, photocurrent and electroluminescence under a wide range of temperatures (77 K – 500 K), light excitation (210 nm – 2200 nm) and ambient conditions (vacuum, N2, air) are also available in the device facility. Such characterization techniques (TOF, CELIV, TSC, POCKELS, etc) can be used to investigate a wide range of materials ranging from inorganic, hybrid, or organic semiconductors to conductive oxides; and as well on optoelectronic devices such as detectors, solar cells, field effect transistors and organic/inorganic LED.
THE CHEMISTRY RESEARCH FACILITY’s major focus is the design and synthesis of new materials. In detail, the research activities of the FACILITY aim at the:
¤ development of nano delivery systems for the control release of bioactive compounds. Our skills concern both the development of new nano-encapsulation methods and the design and synthesis of new nanostructured biomaterials.
¤ Synthesis of functional dyes, new π-conjugated molecules for highly desirable optoelectronic, photovoltaic and bio-imaging probes.
¤ Development of innovative synthesis approaches to colloidal inorganic nanocrystals, made of plasmonic, magnetic or semiconductor materials, with precisely engineered compositional, structural and geometric features and predictable chemical-physical properties.
¤ Development and characterization of colloidal all-inorganic multicomponent heterostructured nanocrystals, in which domains of different materials are assembled together via epitaxial bonding interfaces.
¤ Self-assembly of colloidal nanocrystals having well-defined facets or anisotropic shapes, which can be arranged into a multitude of higher-order assembly structures.
The FACILITY is located on the upper level of the BUILDING B of the CNR NANOTEC and is divided into three operative areas: the Organic Functional Material Laboratory, the Nanochemistry Laboratory and the Material Characterization Laboratory. The FACILITY’s instrumentations include: equipments for material growth, techniques for structural, morphological and compositional characterization, techniques for UV-VIS-IR spectroscopic analysis and analytical instruments for chemical characterization (separation, identification and quantification) of organic/inorganic materials. All such equipments are available for research. If you think you would benefit from access to one or more of the FACILITY’s trained-user instruments you should contact the staff to discuss which system will best meet your requirements and the economic terms of access or alternatively to launch a cooperative agreement. Possibly, an appropriate training might then be arranged. The staff also provides commercial services to industry where possible. Services include: consultancy, full analysis with report, provision of data only, in-house equipment training, consultancy.
The characterization facility includes several laboratories where the large equipments for the advanced characterization of nano-materials and devices is concentrated. In particular, it include two transmission electron microscopes for the study of nanomaterials, a confocal and a STED microscope for bioimaging studies, a laboratory for scanning probe microscopy, a XRD system for crystallographic analysis, a NMR system for molecular characterization in liquid, superconducting magnets (10 mK, 10.5T), cryogenic probe stations and electronics for spintronics and nanomagnetism. The facility is completed by a preparative laboratory and two laboratories for lab on chip (for sensing and microfluidics).
The photonic facility cover a different research areas in modern optics and photonics spanning from basic to application-oriented research. These fields range from plasmonics to polaritonics having as central focus the strong light-matter interaction.
The laboratories are equipped with state of the art instrumentation such as ultrafast and single mode lasers, high power pulse sources, high resolution imaging spectrometers for microPL measurements and different cryostats working from room temperature to 4 K with magnetic fields up to 9 T
The “Biology Facility” consists of four main areas, named Nanobiotechnology, Cell Culture, Microscopy and Electrospinning Laboratories. The Nanobiotechnology Laboratory is dedicated to synthesis of organic/inorganic micro- and nano-capsules, fabrication of polymeric scaffolds, surface functionalization with biomolecules, cells and microorganism treatments, proteins and DNAs extraction/analysis, DNA and cDNA cloning, PCR and biochemical, histochemical/immunohistochemical assays. In the Electrospinning Laboratory nanofibers for biomedical applications are produced. In the Cell Culture Laboratory eukaryotic cells are manipulated. The Microscopy Laboratory is equipped with fluorescence microscopes, flow cytofluorimeters and time-lapse to study living and fixed cells.
