Description

Miguel Crespillo Almenara, estudiante de Doctorado del CMAM, presenta su Tesis "Daño por excitación electrónica mediante irradiación con iones pesados de alta energía en niobato de litio: Mecanismos y nanoestructuración para aplicaciones fotónicas." en la Facultad de Ciencias de la Universidad Autónoma de Madrid, el 12 de Diciembre a las 12:00h.

Abstract:

The aim of the Thesis is to study the origin, main features and potential applications of the damage produced by high density electronic excitation under high energy heavy ion irradiation (i.e. swift heavy ions). From the fundamental point of view it discusses the different mechanisms responsible for the observed damage. This has been addressed under some specific modelling and by studying the thermal stability of the electronic damage.

The unique nanostructuring capabilities offered by the damaged ion tracks (nanometer diameter and microns length) has been exploited to study, in LiNbO3, the fabrication of special nanopores structures and thick (up to ~ 40 µm) optical waveguides based on nanostructured effective optical medium obtained at ultralow fluence (~1011 at/cm2).
This research has been carried out at the Centro de Micro-Análisis de Materiales (CMAM) of the UAM where most of the ion irradiations (with ion energies up to 50 MeV) have been performed. Some very high energy irradiations (~1000 MeV) have been performed at GANIL (Caen, France) and GSI (Darmstadt, Germany).
