Abstract:
This thesis details the development of a 6.2 eV laser-based time- and angle-resolved photoemission spectroscopy (TR-ARPES) apparatus with micro-scale spatial resolution for the study of equilibrium and non-equilibrium properties of inhomogeneous and exfoliated samples. To demonstrate the performance of this apparatus, we spatially resolve the sample inhomogeneities giving rise to spectral broadening of the surface state of the topological insulator Bi2Se3 observed when increasing the spot-size of the 6.2 eV source incident on the sample surface.
