1. 21. Concentrated Solar Thermal Plant for Future Fuels Production : Process Modeling and Techno-economic Analysis of Syngasoline, Syndiesel, Ethanol and Methanol Production Using Thermochemical Cycle based on Metal Oxide

   University essay from KTH/Kraft- och värmeteknologi

   Author : Philipe Gunawan Gan; [2018]
   Keywords : ;

   Abstract : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). READ MORE

3. 22. Using gallium nitride nanowires as STM probes

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

   Author : Karolis Sulinskas; [2018]
   Keywords : STM; STS; Nanowire; GaN; InAs; Semiconductors; Physics and Astronomy;

   Abstract : Gallium nitride (GaN) nanowires grown using catalyst-free metal organic vapor phase epitaxy were used as scanning tunneling microscope (STM) probes. The probes were prepared by placing a GaN nanowire on a tungsten STM probe using a nanomanipulator in a scanning electron microscope (SEM) and welding them together using an electron beam induced platinum deposition.

4. 23. 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

5. 24. Time-Multiplexed Channel Switches for Dynamic Frequency Band Reallocation

   University essay from Linköpings universitet/Datorteknik

   Author : Roland Stenholm; [2016]
   Keywords : parallel; interleaver; bitonic; sorter; clos; network; sts; switch; dfbr; dynamic; frequency; band; reallocation;

   Abstract : A partially parallel reconfigurable channel switch is constructed for use in DFBR. Its permutation can be changed while running without any interruption in the streams of data. Three approaches are tried: one based on asorting network, one based on memories and multiplexers and one based on a Clos network. READ MORE

6. 25. 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
