Self-Assembly of Colloidal Spheres with Specific Interactions
(2014-06-06)
In this thesis, I discuss engineering colloidal particles to have specific, isotropic interactions and studying their cluster geometries in equilibrium. I discuss light scattering experiments showing that a highly specific ...
Carbon Nanotubes for the Generation and Imaging of Interacting 1D States of Matter
(2014-06-06)
Low-dimensional systems in condensed matter physics exhibit a rich array of correlated electronic phases. One-dimensional systems stand out in this regard. Electrons cannot avoid each other in 1D, enhancing the effects of ...
Nanoscale Magnetic Imaging with a Single Nitrogen-Vacancy Center in Diamond
(2013-03-18)
Magnetic imaging has been playing central roles not only in fundamental sciences but also in engineering and industry. Their numerous applications can be found in various areas, ranging from chemical analysis and biomedical ...
First-Principles Multiscale Investigation of Structural and Chemical Defects in Metals
(2013-03-08)
This thesis explores multiscale approaches to describe structural and chemical defects in metals. Particular emphasis is placed on investigating processes involving grain boundaries (GBs) in combination with impurity and ...
Cooperativity, Fluctuations and Inhomogeneities in Soft Matter
(2013-09-30)
This thesis presents four investigations into mechanical aspects of soft thin structures, focusing on the effects of stochastic and thermal fluctuations and of material inhomogeneities. First, we study the self-organization ...
Hot Carriers in Graphene
(2014-10-22)
When energy relaxation between electrons and the lattice is slow, an elevated electronic temperature different from that of the lattice persists. In this regime, hot charge carriers control the energy transport in a material. ...
Two-Dimensional Plasmonics in Massive and Massless Electron Gases
(2014-10-21)
Plasmonic waves in solid-state are caused by collective oscillation of mobile charges inside or at the surface of conductors. In particular, surface plasmonic waves propagating at the skin of metals have recently attracted ...
