Development of a method to determine oxygen distribution in industrial monocrystalline silicon ingots
(Master thesis, 2016)An alternative method to determine oxygen concentration in industrial monocrystalline silicon has been developed and tested, resorting to statistical analysis and modeling. The model has been applied to different set ... -
Grain refinement of commercial EC Grade 1070 Aluminum alloy for electrical application
(Master thesis, 2014)The aluminium alloys for electrical conductivity applications are not grain refined since the addition of grain refiners might decrease their electrical conductivity by inserting impurities into the melt. Still, non-grain ... -
The role of silicon nitride crucible materials on silicon ingots contamination
(Master thesis, 2017)This work focuses on the characterisation of the solid diffusion mechanism of iron and titanium impurities in a silicon nitride crucible, as a substitute for silica crucibles currently used for solar cells production. This ... -
The effect of Zr and V on the structural and mechanical properties of the 2618 Al alloy
(Master thesis, 2014)During the last decades, the use of aluminium components for automotive applications has continuously increased. The main reason for this success is the high strength-to-weight ratio which characterizes these alloys, and ...
