Bi surfactant mediated growth for fabrication of Si,Ge nanostructures and investigation of Si,Ge intermixing by STM
… Moreover, it is also possible to study Ge/Si intermixing in surface layers in some detail. Any attempt to utilize surfactant mediated growth must be preceded by a thorough study of its effect on the the system being investigated. Thus, the third chapter of this thesis deals with an extensive …

Studies of intraorganelle dynamics: the lysosome, the pre-lysosomal compartment, and the golgi apparatus
… a t<sub>½</sub> of ~30 min. Lysosomal content intermixing, shown by a sensitive invertase-lysosome/[¹⁴C]-sucrose-lysosome pairing assay, was inhibited greatly by ATP inhibitors and partially by cytochalasin D. Lysosomal membrane protein intermixing was shown by the transfer of LAMP-2, a mouse …

Identification and optimization of mixed light emitting layers in phosphorescent multilayer OLEDs
… layer. Existing techniques for the detection of intermixing are very expensive and time consuming. In the second part of this thesis, it was tested whether impedance spectroscopy can be used as a suitable and cheap tool to measure the degree of intermixing between two layers. Measurements of the …

In-Situ Behavior of Geosynthetically Stabilized Flexible Pavement
… road aggregate and the underlying subgrade from intermixing. It has been hypothesized that in the absence of a geotextile, intermixing between base course aggregate and soft subgrade occurs. Nine heavily instrumented flexible pavement test sections were built in Bedford County Virginia to …

Theory and simulation of quantum nanostructures for integrated photonics
… develop a multi-component diffusion theory of QW intermixing for quaternary alloy systems. QW intermixing via post-growth annealing enables integration of active and passive components in photonic integrated circuits. QW intermixing generally produces a blueshift of the QW band gap, rendering the …

Post-growth spectral tuning of InGaAs/GaAs quantum dot infrared photodetectors
… optimisation of the device architectures. Intermixing shifts the response of InGaAs/GaAs quantum dot infrared photodetectors, so it is an effective approach to spectral tuning. Dielectric capping layers can be used to control the amount of intermixing and this allows multicolour detectors …

Phase stability in ti/bcc multilayered thin films
… layer thickness, composition and chemical intermixing on the phase stability are determined. In situ thin film growth stresses of these materials are measured and correlated to the interfacial stress evolution to help rationalize the stability behavior. X-ray and electron diffraction have …

The Growth And Magnetic Properties Of Metal Overlayer Systems: Palladium/copper(100), Iron/aluminum(100) And Iron/sulfur/gallium Arsenide(100)
… industrial interest, but results in the intermixing of As into the Fe overlayer. In this study, S-passivated GaAs(100) was examined as a potential substrate for the growth of Fe overlayers. The use of this substrate was found to successfully prevent the intermixing of As with the Fe …

Atomic resolution studies of oxide superlattices and ultrathin films
… of thin films, especially interface sharpness, intermixing, defects, and strain, layering sequence in the case of superlattices and the density of interfaces relative to the film thicknesses. To understand the relationship between the interfacial thin film oxide atomic structure and its …

Niobium-Tantalum Superlattices Grown by Molecular Beam Epitaxy: Structure, Transport, and Superconducting Properties
… was strongly direction dependent. The extent of intermixing was larger than predicted by simple diffusion, indicating mixing due to the kinetics of the deposition process.

Three essays on public economics
… advantage over homogeneous communities, the intermixing of rich and poor generates an efficiency loss in public consumption. As a result, a mixed community configuration may or may not be superior to a homogeneous configuration.

Optical properties of SiGe nanostructures
… the Ge NW - Si substrate interface, where SiGe intermixing has been detected. This interface is formed differently for (111) and (100) oriented Si substrates due to the <111> preferential growth direction of Ge NWs.
