1. 1. The Collective Dynamics of Organizational Learning: On Plurality and Multi-Social Structuring

   Författare :Kristina Henriksson; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organizational science; Transmanche-Link; Channel Tunnel; project; diversity; multi-social structuring; negotiations of meaning; sensemaking; plurality; interorganizational; cross-cultural; knowledge; organizational learning; culture; Organisationsteori;

   Sammanfattning : The notion of organizations as learning entities has gained considerably in popularity over the last decade, and is now regarded an important issue both theoretically and in practice. Many organizational activities and events have been referred to as learning phenomena, and learning theory is being applied to increasingly varied and complex settings of organizational life.

3. 2. Spin-dependant transport in lateral nano-devices based on magnetic tunnel junctions

   Författare :Mattias Urech; Vladislav Korenivski; Bernard Dieny; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spin diffusion; magnetic tunnel junctions; Physics; Fysik;

   Sammanfattning : This thesis is an experimental study of spin dependent transport in nanoscale ferromagnetic tunnel junction arrays and lateral multi-terminal devices with normal metal and superconducting spin transport channels. Two-, three-, and five-junction arrays have been fabricated in the form of lateral circuits and characterized using variable temperature magneto-transport measurements. LÄS MER

4. 3. Vertical III-V Nanowire Tunnel Field-Effect Transistor

   Sammanfattning : In this thesis fabrication and optimization of vertical III-V Tunneling Field-Effect transistors was explored. Usage of vertical nanowires, allows for combination of materials with large lattice mismatch in the same nanowire structure. LÄS MER

5. 4. Integration of Ferroelectric HfO2 onto a III-V Nanowire Platform

   Författare :Anton E. O. Persson; Nanoelektronik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferroelectricity; ferroelectric FET; ferroelectric tunnel junction; tunnel field effect transistors; HZO; III-V; nanowire;

   Sammanfattning : The discovery of ferroelectricity in CMOS-compatible oxides, such as doped hafnium oxide, has opened new possibilities for electronics by reviving the use of ferroelectric implementations on modern technology platforms. This thesis presents the ground-up integration of ferroelectric HfO2 on a thermally sensitive III-V nanowire platform leading to the successful implementation of ferroelectric transistors (FeFETs), tunnel junctions (FTJs), and varactors for mm-wave applications.

7. 5. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure

   Författare :Borja Rojo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbine Rear Frame; Turbine Exhaust Case; Experimental; Exit Guide Vane; Engine Exit Structure; Aerodynamics; Outlet Guide Vane; Gas Turbine; Wind Tunnel; Heat transfer.; CFD; Turbine Rear Structure;

   Sammanfattning : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.
