  3. 3. Spectroelectrochemical analysis of the Li-ion battery solid electrolyte interphase using simulated Raman spectra

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Edvin Andersson; [2020]
    Nyckelord :Lithium Ion Battery; Solid Electrolyte Interphase; Surface Enhanced Raman Spectroscopy; Density Functional Theory; LIB; SEI; SERS; DFT;

    Sammanfattning : Lithium Ion Batteries (LIBs) are important in today's society, powering cars and mobile devices. LIBs consist of a negative anode commonly made of graphite, and a positive cathode commonly made from transition metal oxides. Between these electrodes are separators and organic solvent based electrolyte. LÄS MER

  4. 4. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Nathan Ullberg; [2020]
    Nyckelord :backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

    Sammanfattning : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.
