Time- and Angle-Resolved Photoelectron Spectroscopy of Solar Materials

Natural foundations defining the manner in which a solid material interacts with optical radiation are primarily encoded in the material's momentum-dependent band structure and the microscopic details of the electron-lattice interactions. An access to this ...

Temperature-dependent electron-phonon coupling in La_{2−x}Sr_{x}CuO_{4} probed by femtosecond x-ray diffraction

Majed Chergui, Henrik Moodysson Rønnow, Fabrizio Carbone, Paul Beaud, Krunoslav Prsa, Giulia Fulvia Mancini, Mathieu Julien Gino Cottet, Kazimierz Conder

The strength of the electron-phonon coupling parameter and its evolution throughout a solid's phase diagram often determines phenomena such as superconductivity, charge- and spin-density waves. Its experimental determination relies on the ability to distin ...

Fermi surface determination from wavevector quantization in LaSrCuO films

Davor Pavuna, Claudia Cancellieri, Ping-Hui Lin

We have observed the wavevector quantization in LaSrCuO films thinner than 12 unit cells grown on SrTiO3 substrates. Low energy dispersions were determined in situ for different photon energies by angle resolved photoemission spectroscopy. From the wavevec ...

The growth by laser ablation and electronic properties of thin cuprate films : Bi2Sr2-xLaxCuO6 and La2-xSrxCuO4

Claudia Cancellieri

In my thesis work I have concentrated on the growth and the in-depth analysis of high temperature superconducting thin films with the central aim to elucidate their electronic properties, predominantly by in-situ angle resolved photoemission spectroscopy ( ...

Polarons and confinement of electronic motion to two dimensions in a layered manganite

Henrik Moodysson Rønnow

A remarkable feature of layered transition-metal oxides-most famously, the high-temperature superconductors-is that they can display hugely anisotropic electrical and optical properties (for example, seeming to be insulating perpendicular to the layers and ...
