The Ever Expanding Photoemission Toolbox

From its origins as curious illustration of the photo-electric effect (Einstein, ca. 1905) and later through application as a tool for chemical analysis (Seigbahn, ca. 1967), photoemission spectroscopy has more recently developed into a very versatile tool for solid state physics. A continually improving understanding, paralleled by continually improving instrumentation is both increasing the prominence of photoemission, and broadening its relevance.

In this talk, I will briefly present a broad range of examples from my own recent and continuing work: 1. The role of XPS and resonant XPS in understanding systems as diverse as chemotherapy drug delivery and intermediate band photovoltaics. 2. Angle resolved photoemission (ARPES) as a tool for understanding surface and non-surface localised confined states for organic electronics and quantum computation applications. 3. Spin-resolved ARPES for a fundamental understanding of topological insulators and related spin-orbit coupled systems. 4. Engineering novel confined systems using photoemission microscopy, and 5. Creating and understanding novel phonon interactions through a combination of ARPES, many-body simulations and transport measurements.

With the ongoing developments in synchrotron facilities at Aarhus University and elsewhere, I aim to demonstrate the potential of photoemission related techniques for a broad range of research activities.

The lecture is part of the INASCON 2014 programme
