  3. 22. Graphene: Applications in Surface Science Studies

    Författare :Virginia Boix; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Surface Science; EBID; Catalysis; undercover catalysis; XPS; APXPS; STM;

    Sammanfattning : This thesis addresses how graphene can be a valuable asset for surface science studies. Using a combination of X- ray photoelectron spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, we take advantage of graphene’s sensitivity to changes in its chemical environment to obtain an atomic scale understanding of different reactions occurring above and below the film.

  5. 24. Quantum Correlations and Temperature Fluctuations in Nanoscale Systems

    Författare :Fredrik Brange; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum transport; electronic entanglement; nanoscale thermodynamics; quantum calorimetry; Fysicumarkivet A:2019:Brange;

    Sammanfattning : This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes.
