  1. 11. Critical Assessment of the Mineralogical Collections at Uppsala University using Raman Spectroscopy

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Yuliya Zhuk; [2017]
    Keywords : Raman spectroscopy; gemmology; geology; mineralogy; Mineralogical Collectio; Ramanspektroskopi; gemologi; geologi; mineralogi; mineralogisk samling;

    Abstract : The technique of Raman spectroscopy was applied in order to identify and characterize the number of minerals in the mineralogical collection at the Department of Earth Sciences. The collection was broadened with five rare carbonates borrowed from the collection of the Swedish Museum of Natural History in Stockholm. READ MORE

  3. 12. Understanding Sn-seeded InSb nanowire growth

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

    Author : Hengfang Zhang; [2017]
    Keywords : Science General;

    Abstract : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. READ MORE

  4. 13. Electrical characterization of strained InP-Ga(x)In(1-x)As core-shell nanowires

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

    Author : Lorenz Frevel; [2016]
    Keywords : nanowire; strain; piezoelectric effect; indium phosphide; InP; gallium indium arsenide; GaInAs; InGaAs; core-shell; radial heterostructure; Physics and Astronomy;

    Abstract : This project report attempts to measure the piezoelectric effect in strained core-shell nanowires. The core material is wurtzite indium phosphide (InP) and the shell material wurtzite gallium indium arsenide (Ga(x)In(1-x)As). READ MORE

  5. 14. Characterization of Terahertz Radiation Generated in an Organic Crystal

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

    Author : Åsa Bengtsson; [2016]
    Keywords : Nonlinear optics; Terahertz radiation generation; Optical rectification; Difference frequency generation; Organic crystal; DSTMS; Physics and Astronomy;

    Abstract : The terahertz region of the electromagnetic spectrum is an important research area allowing insights into fundamental science such as inter-molecular interactions, and with applications in the environmental, medical and security field. Using femtosecond lasers, it is possible to design compact and efficient terahertz generation schemes, resulting in few-cycle broadband pulses. READ MORE

  6. 15. Lithiated organic electrode material : Theoretical characterization of structure and electronic band structure

    University essay from Uppsala universitet/Materialteori

    Author : David Gabro; [2016]
    Keywords : ;

    Abstract : This research analyzes the possibility of using lithiated benzenedipropiolate, an organic material, as a replacement for today’s anode materials in lithium batteries. To theoretically analyze the electronic band structure and characterize the structure of the molecule this study used a super computer located in Linköping, Sweden. READ MORE
