1. 1. Electron transport properties of graphene and graphene field-effect devices studied experimentally

   Författare :Youngwoo Nam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dual-gated graphene field effect devices; thermopower; quantum Hall effect; graphene; Aharonov-Bohm effect; chemical vapour deposition;

   Sammanfattning : This thesis contains experimental studies on electronic transport properties of graphene with the Aharonov-Bohm (AB) effect, thermopower (TEP) measurements, dual-gated graphene field effect devices, and quantum Hall effect (QHE). Firstly, in an effort to enhance the AB effect in graphene, we place superconducting-metal (aluminium) or normal-metal (gold) mirrors on the graphene rings. LÄS MER

3. 2. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

   Sammanfattning : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.

4. 3. Jag är icke heller en : den svenska dagboksromanen

   Författare :Maria Wahlström; Göran Rossholm; Kristina Fjelkestam; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Swedish diary novel; diary fiction; Fredrika Bremer; Hjalmar Söderberg; Eyvind Johnson; mimetic genre; mirror effect; self-writing; Literature; litteraturvetenskap;

   Sammanfattning : The aim of this thesis is to examine and describe the Swedish diary novel. The examination and description is based on an inventory of diary fiction written and published in Swedish between 1825 and 2010. The novels are discussed from a narratological point-of-view in the first part of the thesis. LÄS MER

5. 4. MHD Stability and Confinement of Plasmas in a Single Mirror Cell

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; MHD; plasma confinement; magnetic mirror; adiabatic particle motion; adiabatic invariants; Teknisk fysik; Engineering physics; Teknisk fysik;

   Sammanfattning : Thermonuclear fusion is a promising energy source for the future. If an economically efficient thermonuclear reactor would be built it has to be a cheap, safe, and highly productive electric power plant, or, a heating plant. LÄS MER

7. 5. Vertical III-V Nanowire Tunnel Field-Effect Transistors : A Circuit Perspective

   Författare :Gautham Rangasamy; Nanoelektronik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-Power Electronics; Self-Heating; Steep Slope Devices; Tunnel Field-Effect Transistors; Vertical Nanowire; III-V Semiconductors;

   Sammanfattning : The energy scaling of integrated circuits has reached its limit because the operating voltage of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) based switches has reached its minimum value. MOSFETs are limited by thermionic emission and cannot achieve a subthreshold swing (SS) below 60 mV/decade at room temperature. LÄS MER
