  2. 1. Electron Transport in Nanowire Quantum Devices

    Author : Henrik Nilsson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Spin-orbit coupling; the Kondo effect; the Zeeman effect; Quantum dots; Nanowire memories; Nanowire transistors; InSb; InAs; Nanowires; Electron transport; Andreev reflections; Nanowire RF-SET; Noise in nanowires;

    Abstract : This thesis focuses on electron transport in semiconductor InAs/InP and InSb nanowire quantum devices. However, first the temperature dependence of classical charge transport in InSb nanowire field-effect transistors, FETs, is characterized, using InAs nanowire FETs as a reference. READ MORE

  4. 2. YBCO nanowires to study nanoscale ordering in High-Tc Superconductors

    Author : Riccardo Arpaia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoscale ordering; nanoSQUIDs; nanowires; High-Tc superconductors; ultrathin films; oxygen doping; nanowire-based single photon detectors;

    Abstract : We present the realization of YBa2Cu3O7-δ (YBCO) nanowires for both basic physics studies, which could help to elucidate the microscopic mechanisms of High critical Temperature Superconductors (HTS), and for novel applications.The first part of the thesis describes an improved nanopatterning procedure, based on e-beam lithography in combination with an amorphous carbon mask and a very gentle Ar+ ion etching.

  5. 3. Noise and electrical properties of YBCO nanostructures

    Author : Edoardo Trabaldo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; YBCO; noise; HTS; nanowire.; SQUID;

    Abstract : This thesis work deals with the investigation of noise properties in cuprate High critical Temperature Superconductor (HTS) YBCO nanoscale devices. Here the aim is to get a better understanding of nanoscale fluctuations in the normal state of HTS from which superconductivity evolves. READ MORE

  6. 4. Vertical III-V Nanowires For In-Memory Computing

    Author : Saketh Ram Mamidala; Nanoelektronik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RRAM; 1T1R; gate all-around; MOSFET; III-V nanowire; In-memory computing;

    Abstract : In recent times, deep neural networks (DNNs) have demonstrated great potential in various machine learning applications,such as image classification and object detection for autonomous driving. However, increasing the accuracy of DNNsrequires scaled, faster, and more energy-efficient hardware, which is limited by the von Neumann architecture whereseparate memory and computing units lead to a bottleneck in performance.

  7. 5. Nanofabricated Devices Based on Molecular Motors: Biosensing, Computation and Detection

    Author : Mercy Lard; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biocomputing; actin; hollow nanowires; molecular concentration; molecular motors; nano-biosensor; myosin; nano-fabrication; nanowires; Fysicumarkivet A:2014:Lard;

    Abstract : The thesis describes the use of molecular motors in nanofabricated devices designed for potential applications in biosensing, computation and detection. We utilize the well-established guiding principles for controlling the motion of actin filaments propelled by myosin molecular motors, and build upon these developments in order to improve upon previously demonstrated techniques, and establish new methods that, we believe, offer significant progress in these fields.
