Modeling and simulation of phase-transitions in multicomponent aluminum alloy casting

Ten Cate, A. (author), Geurts, B.J. (author), Muskulus, M. (author), Köster, D. (author), Muntean, A. (author), Van Opheusden, J. (author), Peschansky, A. (author), Vreman, B. (author), Zegeling, P. (author)

The casting process of aluminum products involves the spatial distribution of alloying elements. It is essential that these elements are uniformly distributed in order to guarantee reliable and consistent products. This requires a good understanding of the main physical mechanisms that affect the solidification, in particular the thermodynamic...

Charge transport through single molecules in two- and three-terminal mechanical break junctions

Martin, C.A. (author)

During the past decades the downscaling of integrated circuits has been governed by Moore's law, which predicts device dimensions on the order of 10 nm in 2020. Fundamental research in molecular electronics explores the possibility of fabricating such nanoscale devices from single molecules, which offer the prospects of chemical tunability and...

Electron spins in nanowire quantum dots

Van Tilburg, J.W.W. (author)

For small magnetic memories, the ultimate limit is a single magnetic particle, a single electron spin. A lot of research is put in developing devices that can utilize such a single spin memory. At the same time, there is also interest from a more fundamental point of view: on these small scales, Quantum Mechanics starts to play a role. Devices...

Development of Quantitative electron nano-diffraction

Kumar, V. (author)

This thesis is a step towards development of quantitative parallel beam electron nano-diffraction (PBED). It is focused on the superstructure determination of zig-zag and zig-zig NaxCoO2 and analysis of charge distribution in the two polymorphs Nb12O29 using PBED. It has been shown that quantitative electron nano-diffraction (parallel beam) has...

Quantum control of single spins and single photons in diamond

Van der Sar, T. (author)

This thesis describes a series of experiments on the control of the optical properties of the nitrogen-vacancy (NV) center in diamond, and on control of the electron and nuclear spin states associated with the NV center. The NV center is a fluorescing atomic defect center in diamond, consisting of a substitutional nitrogen atom adjacent to a...

Magneto-mechanical dynamics at the nanoscale

Bretzel, S. (author)

Gyromagnetic experiments, the Barnett effect (magnetization by rotation) and the Einstein-de Haas effect (rotation by magnetization), were initially devised to test the molecular current hypothesis and determine the electron g-factor at the dawn of quantum mechanics. Advances in fabrication techniques and an ever increasing control of materials...

In situ Electrical measurements in Transmission Electron Microscopy

Rudneva, M. (author)

In the present thesis the combination of real-time electricalmeasurements on nano-sampleswith simultaneous examination by transmission electron microscope (TEM) is discussed. Application of an electrical current may lead to changes in the samples thus the possibility to correlate such changes with the corresponding I-V measurements is very...

Nanoscale mechanical resonators and oscillators

Van Leeuwen, R. (author)

In this thesis the physics of nanoscale mechanical resonators and oscillators is studied. We discuss two types of resonators. First, a top-down fabricated doubly clamped beam resonator with an integrated piezoelectric actuator is introduced. The second type of resonators are based on layered two-dimensional materials, such as graphene and...

Quantum magnetism through atomic assembly

Spinelli, A. (author)

This thesis presents an experimental study of magnetic structures, composed of only a few atoms. Those structures are first built atom-by-atom and then locally probed, both with a low-temperature STM. The technique that we use to assemble them is vertical atom manipulation, while to study their physical properties we use inelastic electron...

Quantum Pumping and Adiabatic Transport in Nanostructures

Wakker, G.M.M. (author)

This thesis consists of a theoretical exploration of quantum transport phenomena and quantum dynamics in nanostructures. Specifically, we investigate adiabatic quantum pumping of charge in several novel types of nanostructures involving open quantum dots or graphene. For a bilayer of graphene we find that at the Dirac point and for a wide...

Electrodynamics of strongly disordered superconductors

Coumou, P.C.J.J. (author)

Thin films of superconducting materials with a high resistance in the normal state, such as TiN, NbTiN, NbN and InO, are intensively studied from both an application and a fundamental point of view. A spatially inhomogeneous superconducting state can arise in these materials as a result of the strong disorder. This Thesis provides an...
