  1. 1. Spin Transport in Two-Dimensional Material Heterostructures

    Författare :André Dankert; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black phosphorous; Topological insulator; h-BN; Silicon; Transistor; Spintronic; MoS2; Graphene; 2D materials; Spin polarized tunnelling; Schottky barrier;

    Sammanfattning : Spintronics is considered as an alternative for information processing beyond the charge based technology. The spintronic device performance depend on the spin relaxation mechanisms in the channel material. Si and graphene are interesting for their long spin coherence lengths and ideal for spin transport channels. LÄS MER

  3. 2. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Författare :Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Sammanfattning : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. LÄS MER

  4. 3. Comparative Study of different Recycling Methods for the Electrolyte Recovery from spent Li-Ion Batteries
