    Sammanfattning : Electronics such as microprocessors are highly demanded to monitor or control a process or operation in temperature critical (300 ºC to 600 °C) applications. State-of-the-art silicon-based integrated circuits (ICs) have been improved significantly throughout the years but mainly for a low-temperature ambient. LÄS MER

  3. 12. Studies of Light Emitting Devices Based on Er-doped Si and SiGe Layered Structures

    Författare :Chun-Xia Du; Fransesco Priolo; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electroluminescence; diode; transistor; hot electron; recombination; excitation; de-excitation; Auger effect; molecular beam epitaxy; Er; Si; SiGe;

    Sammanfattning : Doping with rare earth element erbium (Er) in Si has recently attracted a lot of research interest due to potential applications in Si-based opto-electronics. By using molecular beam epitaxy (MBE), precipitate-free Er-doping in Si has been made together with other co-dopants, e.g., oxygen (0) and fluorine (F), up to a level ∼1020 cm-3. LÄS MER

  4. 13. Novel Processing and Electrical Characterization of Nanowires

    Sammanfattning : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. LÄS MER

  5. 14. 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
