A study on commercial SiC-powders sintered by hot pressing
(Master thesis, 2016)Hot-pressing of a commercial silicon carbide powder was performed with 0, 5 and 10wt% added hexagonal boron nitride. Density, microstructural and compositional development has been studied ex situ with different holding ... -
A TEM Study of Boron-implanted Cubic Silicon Carbide, for Solar Cell Applications
(Master thesis, 2016)Recent research suggests that high doses of boron implantation can introduce an intermediate electron energy band in cubic silicon carbide (3C-SiC). This makes it a viable material for a highly efficient intermediate band ... -
BORON REMOVAL FROM MOLTEN SILICON BY GAS BLOWING USING DIFFERENT GAS MIXTURES
(Master thesis, 2016)- -
Carbon-Supported Nanostructured Core-Shell Catalysts for Low Temperature Fuel Cells
(Master thesis, 2015)The direct methanol fuel cell needs a catalyst with low overpotential and high current density for methanol oxidation to be commerically viable. The catalyst with highest performance at the moment is the PtRu-alloy catalyst, ... -
Cristobalite formation on quartz crucibles inner surface for CZ solar cell ingot production
(Master thesis, 2017)Cristobalite, the stable high temperature polymorph of quartz, is formed on the surface of fused quartz crucibles used for the growth of monocrystalline silicon ingots by the Czochralski process. When not controlled and ... -
Development of polymer-nanoparticle composite with high refractive index
(Master thesis, 2016)A newly developed lens technology utilizes a soft high refractive index polymer to change focus. By further increasing the refractive index of the polymer, without lowering the transmittance of visible light, the overall ... -
Master Slag Production for the Recovery of Rare Earth Elements
(Master thesis, 2017)The Rare Earth Elements (REEs) is a term describing a group of 17 elements which are critical components in many technological applications due to their magnetic or optical properties. In contrast to the name, these elements ... -
N-type Czochralski silicon ingots - Oxygen-related defects in the last solid fraction
(Master thesis, 2016)The focus of this master's thesis has been the formation of oxygen-related defects in the last 10 cm before the tail in Czochralski silicon ingots for solar cell applications. For nine industrial standard ingots from ... -
Preparation of Inks for Inkjet Printing of Thin Films in Solid Oxide Fuel Cells
(Master thesis, 2016)Solid oxide fuel cell technology can achieve high efficiency when producing electric power. To produce these fuel cells with a high quality and a low cost, inkjet printing can be utilized. This technique is highly dependent ... -
Sintering of lead-free piezoelectric materials
(Master thesis, 2015)Piezoelectric ceramics are used in many types of devices, and today, lead zirconate titanate (PZT) dominates the market due to its superior properties. Environmental and health concerns have made the search for lead-free ... -
Synthesis and Properties of YBaCo2O5+δ for Solid Oxide Fuel Cell Cathodes
(Master thesis, 2016)The layered double perovskite YBaCo2O5+δ was synthesised and characterised. The synthesis was done by solid-state reaction with several calcination steps at temperatures between 1000°C and 1130°C. The structure was ...
