Plasmonically enhanced molecular junctions for investigation of atomic-scale fluctuations in self-assembled monolayers

Molecular junctions represent a fascinating frontier in the realm of nanotechnology and are one of thesmallest optoelectronic devices possible, consisting of individual molecules or a group of moleculesthat serve as the active element sandwiched between co ...

A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions

Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and plasma-molecule interactions. Experimental research in how those reactions pre ...

Infrared Spectroscopy as a Probe of Electronic Energy Transfer

Thomas Rizzo, Antonio Prlj, Valeriu Scutelnic, Aleksandra Zabuga

We have combined electronic and vibrational spec- troscopy in a cryogenic ion trap to produce highly resolved, conformer-selective spectra for the ground and excited states of a peptide containing two chromophores. These spectra permit us to determine the ...

Adsorption Sites of Metal Atoms on MgO Thin Films and Rotational Quantum State Spectroscopy of Physisorbed H₂

Edgar Fernandes

The work presented in this thesis covers two different topics of surface science, both investigated with the scanning tunneling miscroscopy and spectroscopy at low temperatures (5~K). First, we are interested in the spectroscopic properties of physisorbed ...

Orientation Dependence of Plasmonically Enhanced Spontaneous Emission

Olivier Martin

We computationally explore how the orientation of dipolar emitters placed near plasmonic nanostructures affects their radiative enhancement and spontaneous emission rate. We demonstrate that the expressions for these quantities show a subtle dependence on ...

Vibrational Activation of Methane Chemisorption: The Role of Symmetry

Rainer Beck, Hirokazu Ueta, Phil Morten Hundt, Maarten Eduard van Reijzen

Quantum state-resolved reactivity measurements probe the role of vibrational symmetry on the vibrational activation of the dissociative chemisorption of CH4 on Pt(111). IR–IR double resonance excitation in a molecular beam is used to prepare CH4 in all thr ...

Steric hindrance at metal centre quenches green phosphorescence of cationic iridium(III) complexes with 1-(2-pyridyl)-pyrazoles

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

Cationic cyclometalated iridium(III) complexes (N,C-2'-2-phenylpyridyl)(2)Ir((NN)-N-boolean AND) with alkyl-substituted 1-(2'-pyridyl)-pyrazole (NN)-N-boolean AND ligands exhibit green phosphorescence from a cyclometalating-ligand-centered excited s ...
