The possibility of controlling materials properties by tailoring their substructure at the nanometer scale is a current topic of great interest. To do so, a fundamental understanding of the growth mechanism is of key importance and an analytical challenge ...
This thesis work contains an experimental study of many-body and cooperative effects in quantum wells. Many-body effects prove important for an understanding of the physical and specifically optical properties of semiconductors. The Coulomb interaction bet ...
Identification of proteins in 3D maps of cells is a main challenge in structural cell biology. For light microscopy (LM) clonable reagents such as green fluorescent protein represented a real revolution and equivalent reagents for transmission electron mic ...
This thesis presents an experimental study of the energy and time-resolved optical response of chemically prepared CdSe nanoparticles with different sizes, shapes (dots, rods, and tetrapods), and lattice structures (wurtzite and zinc blende). The first par ...
Following the current interest in transition metal doped dielectrics for spintronic applications, Mn-doped ZnO is being made by thermal decomposition of Mn-doped hydrozincite, (MnxZn1–x)5(OH)6–2n (CO3)1+n, precursors that have been prepared by a novel syn ...
The use of nanomaterials has been shown to be promising in potential applications such as magnetic storage devices, nano-optical devices and sensors, amongst others. Such applications require the disposition of nanoparticles, of a wide variety of materials ...
Tobacco Mosaic Virus (TMV) is composed of 2130 identical coat protein subunits following the right-handed helix of an accompanying RNA strand to produce a 300 nm hollow cylinder with an outer diameter of 18 nm and a 4 nm wide central channel. In this work, ...
This thesis presents an experimental study of the time-resolved optical response of three different nanoscale systems: CdSe and PbSe quantum dots, and silver triangular nanoplates. The first part of the thesis is devoted to the understanding of the effects ...
Photoluminescence (PL) spectroscopy has been demonstrated as a suitable technique to characterize Si nanocrystal-based non-volatile memory devices (Carrada et al. APL 2005). These are formed by a single plane of Si nanocrystals (NCs) buried in the gate oxi ...
Thermal position fluctuations of a colloidal particle in an optical trap are measured with microsecond resolution using back-focal-plane interferometry. The mean-square displacement MSD(t) and power spectral density are in excellent agreement with the theo ...
