  1. 26. Electrical Characterization of Novel Insulators in Metal-Insulator-Semiconductor Structures

    Författare :Anders Jauhiainen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon dioxide; MOS; Fowler-Nordheim injection; charge transport; MIS; wafer bonding; polycrystalline diamond; capacitance;

    Sammanfattning : This thesis comprises seven papers (A-G) and an extended introduction which puts them into context within a broader field of research. The papers deal with the electrical characterization of some different insulators and interfaces encountered within the realm of silicon based microelectronics. LÄS MER

  3. 27. Graphene spin circuits and spin-orbit phenomena in van der Waals heterostructures with topological insulators

    Författare :Dmitrii Khokhriakov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Spin-charge conversion; Topological insulator; Spintronics; Proximity effect; Van der Waals heterostructures;

    Sammanfattning : Spintronics offers an alternative approach to conventional charge-based information processing by using the electron spin for next-generation non-volatile memory and logic technologies. To realize such technologies, it is necessary to develop spin-polarized current sources, spin interconnects, charge-to-spin conversion processes, and gate-tunable spintronic functionalities. LÄS MER

  5. 29. Epigenetic Regulation of the H19 Chromatin Insulator in Development and Disease

    Författare :Claes Holmgren; Rolf Ohlsson; Tomas Ekstöm; Uppsala universitet; []

    Sammanfattning : The coordinated regulation of gene expression must be tightly controlled for normal development to occur. In mammals, this issue is further complicated by the requirement of both the maternal and paternal genomes for normal development, reflecting the fact that a subset of genes are monoallelically expressed depending on parental inheritance, a phenomenon known as genomic imprinting.

  7. 30. Magnetic solotronics near the surface of a semiconductor and a topological insulator

    Författare :Mohammad Reza Mahani; C.M. Canali; Biplab Sanyal; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic solotronics; Transition metal dopants; Dilute magnetism in semiconductors and topological insulators; Atomistic tight-binding models; DFT; Spin dynamics; Magnetic anisotropy; Scanning tunneling microscope.; Condensed Matter Physics; Kondenserade materians fysik;

    Sammanfattning : Technology where a solitary dopant acts as the active component of an opto-electronic device is an emerging  field known as solotronics, and bears the promise to revolutionize the way in which information is stored, processed and transmitted. Magnetic doped semiconductors and in particular (Ga, Mn)As, the archetype of dilute magnetic semiconductors, and topological insulators (TIs), a new phase of quantum matter with unconventional characteristics, are two classes of quantum materials that have the potential to advance spin-electronics technology.
