Buijtendorp, B. (author)We develop a computational method that can efficiently simulate Landau levels in quantum heterostructures, by reducing the problems dimensionality. We then apply this to a GaSb/InAs/AlSb broken gap quantum well in the trivial and inverted regimes. This heterostructure can be tuned into a 2DTI phase, and has possible applications in topological...bachelor thesis 2016

ter Hoeven, R.S. (author)The Kernel Polynomial Method (KPM) is a method to approximate any function as a polynomial of finite order. In this research the KPM will be used to approximate the density of states and expectation values of physical observables in a tight binding system. To be able to use the KPM a tight binding Hamiltonian is obtained by using the python...bachelor thesis 2016

Langerak, N. (author)Electronic devices are downsizing at a rapid pace and since the 1990s, single molecules have been studied as candidates for such devices. This thesis focusses on a new approach to simulate the electric current through these molecular devices. We followed the approach of Hod [17], which is based on the time propagation of the density matrix and...bachelor thesis 2016

Assendelft, J. (author)The aim of this report is to investigate the inelastic tunneling current that would be measured during an inelastic electron tunneling spectroscopy experiment performed on a one dimensional chain of magnetic atoms. A chain consisting of n magnetic iron atomswith spin 2 has been examined. The spins of the iron atoms in the chain have been treated...bachelor thesis 2016

Van Gulik, R.J.J. (author)In this report an overview of the techniques used to perform measurements on a Josephson radiation detector is given. This experiment could lead to the observation of Majorana bound states, which can be used to realize a topological quantum computer. Software for the plotting of data from one- and two-variable measurements was developed, with...bachelor thesis 2016

De Boer, F.Q. (author)Lithium silicon (Li-Si) batteries offer more than ten times the theoretical specific capacity compared to current lithium ion battery technologies, by using a silicon anode. In practice however, the cycle life of Li-Si batteries is very limited. The large volume change of the silicon anode is known to be the main reason for this. Research on the...bachelor thesis 2015

Slim, J.J. (author)A setup was built to measure the local frequency response of (graphene) microdrums in order to image mode shapes. To this end, a laser interferometer that measures the local deflection of a microdrum was equipped with a very precisely movable sample stage. The setup was used to image the mode shapes of a single few layer graphene microdrum,...bachelor thesis 2015

Van Woerkom, D.J. (author)In this Master thesis I report results on a route to find Majorana fermions in indium antimonide nanowires in contact with a superconductor. Theoretically Majorana fermions appear in one-dimensional nanowires with strong spin-orbit coupling, in proximity with a superconductor and an external magnetic field applied parallel to the nanowire. The...master thesis 2012

Hordijk, W. (author)This thesis describes the process of deriving the Master Equation for the time evolution of the density operator for a lead coupled spinless Hubbard chain using a Markov approximation. The derivation is done in a direct, conventional way of expanding operators and switching pictures in order to separate the system Hamiltonian in a convenient way...bachelor thesis 2011

Janssen, R.M.J. (author)Spectroscopic observations of a large number of galaxies in the far-infrared are critical in the study of galaxy evolution. These observations are difficult at the moment, because of the lack of good far-infrared (FIR) detector technology. Microwave Kinetic Inductance Detectors (MKIDs) are showing promising results to fill this void. A common...master thesis 2010
