"Precursors for Rare Earth Oxides - New Routes to ultrathin Oxide Layers"

Mathias Wickleder
Department of Chemistry,
University of Cologne,
Germany

Abstract
Rare earth oxides have attracted considerable attention as so called high-k materials. These compounds exhibit very high dielectric constants that are mandatory for further miniaturization of electronic devices. Especially for field effect transistors ther e is strong need for ultrathin films of high-k oxides on silicon surfaces. There are several methods to produce these layers, like atomic layer deposition (ALD) and chemical vapor deposition (CVD). Our research is directed to the development of a more simp le process that allows for the preparation of thin carbon-and-chlorine-free layers. Following these aims we are investigating m olecular nitrates and perchlorates according to the general formula M(NO3)3·xL and M(ClO4)3·xL, where M is a rare earth metal an d xL is a variable number of solvent ligands. These compounds usually show the M3+ ions coordinated by three chelating nitrate groups and the solvent molecules leading to high coordination numbers We used the DME compound La(NO3)3·2DME as a precursor for the deposition of La2O3 on H-terminated silicon surfaces. It turned out that the simple procedure leads to La2O3 layers with a thickness below 10 nm.

Spaventapasseri fotonico e spaventapasseri ontologico
Usare la luce per la protezione delle colture

I ricercatori trentini di IFN e ISTC, istituti del CNR (https://www.cnr.it), presentano alcuni dispositivi ottici ed un prototipo compatto e maneggevole che utilizza la luce per spaventare gli uccelli senza l'uso di sostanze chimiche e con basso uso di energia. In parallelo il pubblico potrà confrontarsi con una analisi concettuale di come si concepisce e modella il mondo con e in questi sistemi.

L’evento “Stand hands-on” si terrà presso il MUSE nel quartiere Le Albere a Trento venerdì 27 settembre 2019 dalle 17:00 alle 24:00 nell’ambito delle attività organizzate da FBK, MUSE, FEM e UNITN, con la collaborazione della Provincia Autonoma di Trento in occasione della Notte dei Ricercatori.

Symposium CL
Inorganic Materials Systems for Advanced Photonics

The fruitful exploitation of optical ceramics and glasses and related photonic structures and devices as crucial pivots for the development of several enabling technologies provides a large spectrum of functionalities that allow us to face successfully socio- economic challenges in many fields going from energy production and saving to efficient and clean industrial cycles, from environmental protection to fast efficient novel communication systems, from structural monitoring to quantum technologies and to healthcare applications.
This Symposium, that follows the several ones on similar subject held at previous CIMTEC conferences, is to provide latest insights on fabrication, characterization and exploitation of photonic structures based on ceramics (oxides, oxynitrides, fluorides, sulphides, chalcogenides, etc...) inorganic non-metallic glasses, glass- ceramics, and ceramic/metal and glass/metal combinations in the form of nanostructured, bulk and graded materials and coatings, fibres, thin films, superlattices and other small confined systems, nanomaterials, nanocomposites and functional nanoparticles.
Focus will be on theory, modelling and simulation of materials and processes, green and advanced fabrication protocols (self assembly, particle beams, light irradiation, micromachining, colloidal processing...) and up-to-date characterization of structure, non-linear optical properties, tunability, nanosize effects etc. of novel inorganic photonic materials systems for light generation, detection, and manipulation including e.g. luminescent and laser materials, smart optical fibres, active plasmonic heterostructures, novel confined nano-micro structures etc. covering the UHV-IR electromagnetic spectrum.
Contributions from Academia and industry on upgraded or novel application and prospective new approaches to photonic-based technologies are also firmly encouraged.
