Characterization of a rapid scan FTIR for ultrafast probing in the mid-IR region
(Universitat Politècnica de Catalunya, 2016-09-09)
Projecte Final de Màster Oficial
Accés obertThe properties of materials in the mid-infrared spectral region (3-15 \mu m) is vital for understanding their operation and performance. It is challenging to characterize femtosecond pulses in this spectral region. In this ... -
Holographic imaging of nanometer-scale phase-separation during a phase transition
(Universitat Politècnica de Catalunya, 2019-09-09)
Projecte Final de Màster Oficial
Accés obertQuantum materials is a broad term used in condensed matter physics to define materials whose collective properties are governed by quantum behavior, which are challenging to understand. These materials are sensitive to ... -
The insulator-metal phase transition in VO2 measured at nanometer length scales and femtosecond time scales
(Universitat Politècnica de Catalunya, 2019-05-02)
Tesi
Accés obertThe physics of transition-metal oxides presents a challenge to our current understanding of condensed matter physics. The main difficulty arises from a competition between electron-electron and electron-phonon interactions ... -
Optical control of thermal diffusion in phase change materials
(Universitat Politècnica de Catalunya, 2016-09-09)
Projecte Final de Màster Oficial
Accés obertThe long term crystallization of amorphous Ge2Sb2Te5 (GST) induced by femtosecond laser pulses has been numerically and experimentally studied. Simulations of the evolution of temperature and crystalline fraction after a ...
