FWF funded PhD position:
Orbital Tomography of organic semiconductor films
In the past few years the technique of orbital tomography has been developed and it´s potential power of has been demonstrated; we have shown that it can determine molecular geometries, gain insight into the nature of the surface chemical bond, unambiguously determine the orbital energy ordering in molecular homo- and heterostructures and even reconstruct orbitals in real space. The global aim of this project is to develop and consolidate orbital tomography and provide a basis whereby it could be even more generally applied. It will involve systematic studies of the polarization and energy dependence of the incident photon on the angular (momentum) distribution of photoemitted electrons from a variety of device relevant molecular adsorbate films. It will lead to advances in understanding valence band photoemission in general and the electronic structure of “organic semiconductors” in particular.
The Phd candidate will work with a number laboratory and synchrotron based UHV systems and will also collaborate with the theory group of Peter Puschnig (KFU) and Forschung Zentrum Jülich.
BSc. & MSc. positions:
The focus of this project is on the preparation of low-dimensional ternary oxide MWOx (M denotes
a transition metal: Cu, Ni, Fe, Co, Mn), or so-called tungstate nanostructures, and the
characterization of their properties at the atomic level. For the preparation of the ternary oxide nanolayers a new fabrication approach will be employed, which involves a two-dimensional solid state
reaction process of (WO3)3 cluster molecules, deposited from the gas phase, onto a well-
ordered surface oxide MOx phase in ultrahigh vacuum. The characterization of the structural, electronic and vibrational properties of the tungstate nanostructures will be performed in situ and with
atomic precision using the full palette of modern surface science techniques.
The global aim of this BSc. or MSc. project is to help develop and consolidate orbital tomography and provide a basis whereby it could be even more generally applied.
The BSc. or MSc. student will work with laboratory and/or synchrotron based UHV systems on collaborative projects with the theory group of Peter Puschnig (KFU) and Forschung Zentrum Jülich (GER) through the FWF-funded project concerned with the same topic.
Specific projects, molecules and experimental techniques will be decided upon discussion with the candidate.
