1. 6. Design, construction and modelling of an air cleaning test rig

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Louise Stjern; [2018]
   Keywords : ;

   Abstract : The cleaning technology for exhaust air is an area under constant development. In collaboration with Ozone Tech Systems the project resulted in a lab scale test rig for air cleaning units. READ MORE

3. 7. InAs and high-k oxides, a scanning tunnelling study of their interfaces

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Mattias Åstrand; [2018]
   Keywords : Semiconductor; High-k; Atomic layer deposition; Scanning tunnelling microscopy; Scanning tunnelling spectroscopy; Physics and Astronomy;

   Abstract : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. READ MORE

4. 8. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy

   University essay from KTH/Materialvetenskap

   Author : Edwin Bergstedt; [2017]
   Keywords : Laser welding; AM50; Die Cast; Magnesium; Porosity;

   Abstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE

5. 9. Scanning Tunneling Microscopy and Spectroscopy of the GaSb(111)B surface

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Pontus Littow; [2016]
   Keywords : Physics and Astronomy;

   Abstract : In this thesis the III-V semiconductor material GaSb (111) was studied using Scanning Tunneling Microscopy and Scanning Tunneling Spectroscopy. To characterize the surfaces of semiconductors has become more relevant in today society. When semiconductors become so small that they are in the micro scale the surface must be taken into consideration. READ MORE

6. 10. The Influence of Oxygen on Nanowire Surface Structure and Electronic Properties

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Viktor Abelin; [2015]
   Keywords : Scanning tunneling microscopy; STM; Auger electron spectroscopy; AES; nanowire; hydrogen cleaning; Physics and Astronomy;

   Abstract : This thesis investigates the possibilities for setups measuring how the surface structure of nanowires (NWs) influences their electric properties. For this the abilities to clean surfaces and detect nanowires (NWs) are examined, and an attempt to build a setup is made. READ MORE
