1. 11. EBL Patterned ITO Contacts for Single Nanowire Devices

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Markus Snellman; [2018]
   Keywords : Physics and Astronomy;

   Abstract : Nanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements.

3. 12. Development of Epitaxial Lift-Off to form GaAs nanowire array membranes

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Erik Svensson; [2016]
   Keywords : MOVPE; MOCVD; AlGaAs; 111 B; Epitaxy; ELO; Epitaxial Lift-Off; Technology and Engineering;

   Abstract : Epitaxial lift-off-layers (ELO) were developed in order to create nanowire array membranes, with the intent to pave the way for solar cells in tandem. Ultimately this thesis project focused only on growing and characterizing the ELO layers on (111)B oriented GaAs substrates with MOCVD, as this process step is not thoroughly understood in literature.

4. 13. X-ray diffraction studies on complex metal oxides

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

   Author : Albin Linder; [2015]
   Keywords : reciprocal space; compass; x-ray diffraction; XRD; magnetite; Physics and Astronomy;

   Abstract : The ambition of this project is to assist in the pursuance of understanding the metal to insulator transition found in magnetite at ~120 K. The transition is itself very complex and links together the charge order, orbital order and lattice distortion of magnetite with its magnetic properties. READ MORE

5. 14. Development of a Simulation Methodology for Gas Turbine Combustion

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

   Author : Thommie Nilsson; [2015]
   Keywords : combustion; computational fluid dynamics; reactor network; Physics and Astronomy;

   Abstract : The main goal of this thesis was the development and application of a method to construct reactor networks based on pre-calculated flow fields for combustion systems. Computational fluid dynamics (CFD) was used to calculate flow fields for the Sandia piloted jet flame D and a Siemens SGT-800 gas turbine burner rig. READ MORE

6. 15. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

   University essay from Linköpings universitet/Biosensorer och bioelektronik

   Author : Daniel Falk; [2015]
   Keywords : Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

   Abstract : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. READ MORE
