  1. 1. Mathematical modeling and analysis of hot carrier solar cells

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin van Dijk; [2023]
    Keywords : solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Abstract : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. READ MORE

  4. 3. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

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

    Author : Klára Nováková; [2021]
    Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 4. 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.
