Island, J.O. (author)In this thesis we investigate superconducting hybrids made from two material systems, namely, molecules and layered materials. For studies of superconducting phenomena in molecular junctions we develop two platforms which rely on the superconducting proximity effect to preserve preexisting nanogap formation techniques and bonding chemistries....doctoral thesis 2016

Perinetti, U. (author)This thesis presents different optical experiments performed on semiconductor quantum dots. These structures allow to confine a small number of electrons and holes to a tiny region of space, some nm across. The aim of this work was to study the basic properties of different types of quantum dots made of various materials and with different...doctoral thesis 2011

Liu, X.L. (author)Graphene is an exceptionally thin semiconductor that consists of only one atomic layer of carbon atoms. The electrons in graphene live in a strictly twodimensional (2D) world. In addition to this remarkable 2Dness, it is also peculiar that the behavior of the electrons in graphene is governed by the Dirac equation rather than the well known...doctoral thesis 2010

Götz, G.T.J. (author)We experimentally investigate Quantum Dots, formed in Carbon Nanotubes. The first part of this thesis deals with charge sensing on such quantum dots. The charge sensor is a metallic Singleelectrontransistor, sensitive to the charge of a single electron on the quantum dot. We use this technique for realtime charge readout and precise tuning of...doctoral thesis 2010

Bodoky, F. (author)The goal of this thesis is to investigate theoretically the generation and behaviour of multipartite entanglement for solidstate nanosystems, in particular electron spin quantum bits (socalled 'qubits') in quantum dots. A quantum dot is a tiny potential well where a single electron can be trapped. A quantum bit can be implemented in this...doctoral thesis 2009

Loef, R. (author)Space charges in two heterojunctions (i.e., TiO2/CuInS2 and TiO2/QDCdSe) are studied by means of impedance spectroscopy and capacitance studies. Several lattice defects are found. When applied in solar cells, the defects may have a negative effect on the efficiency. Therefore, it is important to know the nature of the defects. In this thesis a...doctoral thesis 2009
 document

Vink, I.T. (author)Besides an electric charge, electrons also have a tiny magnetic moment, called spin. In a magnetic field, the spin has two possible orientations: 'spinup' (parallel to the field) and 'spindown' (antiparallel to the field) and can therefore be used as a quantum bit, the computational unit of a quantum computer. For quantum computations,...doctoral thesis 2008

Zwanenburg, F.A. (author)The research in this thesis is motivated by an interest in quantum physics and by the prospect of new applications based on the spin of electrons or holes. This work focuses on confining single spins in quantum dots, which can serve as building blocks of a future quantum computer. Such a computer exploits the unique features of quantum mechanics...doctoral thesis 2008
 document

Koppens, F.H.L. (author)An electron does not only have an electric charge, but also a small magnetic moment, called spin. In a magnetic field, the spin can point in the same direction as the field (spinup) or in the opposite direction (spindown). However, the laws of quantum mechanics also allow the spin to exist in both states at the same time (socalled...doctoral thesis 2007

Sapmaz, S. (author)Low temperature electron transport measurements on individual single wall carbon nanotubes are described in this thesis. Carbon nanotubes are small hollow cylinders made entirely out of carbon atoms. At low temperatures (below ~10 K) finite length nanotubes form quantum dots. Because of its small size a quantum dot has a discrete set of energy...doctoral thesis 2006

Van Dam, J. (author)This thesis describes a series of experiments aimed at understanding the lowtemperature electrical transport properties of semiconductor nanowires. The semiconductor nanowires (1100 nm in diameter) are grown from nanoscale gold particles via a chemical process called vaporliquidsolid (VLS) growth. The huge versatility of this material system...doctoral thesis 2006

JarilloHerrero, P.D. (author)Electronic transport through nanostructures can be very different from trans port in macroscopic conductors, especially at low temperatures. Carbon na notubes are tiny cylinders made of carbon atoms. Their remarkable electronic and mechanical properties, together with their small size (a few nm in diameter), make them very attractive for...doctoral thesis 2005

Elzerman, J.M. (author)In this thesis, the spin and charge degree of freedom of electrons in semiconductor lateral and vertical quantum dots are experimentally investigated. The lateral quantum dot devices are defined in a twodimensional electron gas (2DEG) below the surface of a GaAs/AlGaAs heterostructure, by metallic surface gates. The vertical quantum dots are...doctoral thesis 2004

Erlingsson, S.I. (author)The main theme of this thesis is the hyperfine interaction between the many lattice nuclear spins and electron spins localized in GaAs quantum dots. This interaction is an intrinsic property of the material. Despite the fact that this interaction is rather weak, it can, as shown in this thesis, strongly influence the dynamics of electron spins...doctoral thesis 2003

Falub, C.V. (author)Positron annihilation spectroscopy is a powerful method to study materials containing very small concentrations of atomic defects and embedded quantum dots. Depending on the method of producing positrons, there are bulk spectroscopies using fast positrons and depth profiling spectroscopies using slow positrons. Both types of spectroscopies are...doctoral thesis 2002
