2. 1. Technology Platforms: Organizing and Assessing Technological Knowledge to Support its Reuse in New Applications

   Author : Daniel Corin Stig; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology management; knowledge reuse; technology platforms; platform thinking; core capabilities; technology development; technology reuse; technology transfer; knowledge management; knowledge repositories;

   Abstract : Companies that develop a wide range of products often strive to exploit opportunities for synergy among them. Many products that cannot share components can still offer opportunities for synergy as they build upon the same technologies and know-how for their development and production. READ MORE

4. 2. Impact of adjacent dielectrics on the high-frequency performance of graphene field-effect transistors

   Author : Muhammad Asad; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; high-frequency electronics; Graphene; transit frequency; contact resistance; MOGFETs; drift velocity; field-effect transistors; saturation velocity; maximum frequency of oscillation; diamond;

   Abstract : Transistors operating at high frequencies are the basic building blocks of millimeter wave communication and sensor systems. The high velocity and mobility of carriers in graphene can open ways for development of ultra-fast group IV transistors with similar or even better performance than that achieved with III-V based semiconductors.

5. 3. Preparation and characterization of graphene/metal composites

   Author : Kristoffer Harr Martinsen; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; graphene oxide; metal matrix composite; Copper; surface functionalization; anticorrosion.;

   Abstract : Since the isolation of graphene in 2004, much research has been conducted to understand this novel material and how its properties can be utilized in different applications. One type of venture involves graphene as a reinforcing filler in metal matrix composites (MMC) which is becoming increasingly prevalent in the automotive and aerospace industries. READ MORE

6. 4. Out of the Dark and into the Light - Microscopic Analysis of Bright, Dark and Trapped Excitons

   Author : Maja Feierabend; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; density matrix formalism; localized states; impurities; dark excitons; strain; transition metal dichalcogenides; Bloch equations;

   Abstract : Atomically thin transition metal dichalcogenides (TMDs) have been in the focus of current research due to their efficient light-matter interaction, as well as the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of optically accessible bright and inaccessible dark excitons. READ MORE

7. 5. Experimental methods to determine model parameters for failure modes of CFRP

   Author : Daniel Svensson; Ulf Stigh; Svante Alfredsson; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; delamination; energy release rate; compressive failure; cohesive modelling; composite; Teknik; Technology;

   Abstract : The focus of this thesis is to develop methods to predict the damage response of CarbonFibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing costand weight of CFRP components, it is crucial to enable modelling of the non-linearresponse associated with various failure modes. READ MORE
