1. 16. Essays on the Evaluation of Public Policies

   Författare :Michihito Ando; Matz Dahlberg; Che-Yuan Liang; David Neumark; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Local income growth; Local employment; Nuclear power facilities; Synthetic control method; Quantitative case study; Regression kink design; Endogenous treatment; Intergovernmental grants; Flypaper effect; Treatment effect heterogeneity; Instrumental variable; Oral health; Dentures; Price elasticity; Regression discontinuity design; Cost sharing; Randomization test; Economics; Nationalekonomi;

   Sammanfattning : This thesis consists of four self-contained papers.Essay 1: This paper uses the synthetic control (SC) method to examine how the establishment of Nuclear Power Facilities (NPFs) in Japan in the 1970s and 1980s has affected local per capita income levels in the municipalities in which they were located (NPF municipalities).

3. 17. Graphene field-effect transistors and devices for advanced high-frequency applications

   Författare :Marlene Bonmann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traps; graphene; self-heating; field-effect transistors; remote phonons; carrier transport; saturation velocity; microwave devices; impurities and defects;

   Sammanfattning : New device technologies and materials are continuously investigated, in order to increase the bandwidth of high-speed electronics, thereby extending data rate and range of applications. The 2D-material graphene, with its intrinsically extremely high charge carrier velocity, is considered as a promising new channel material for advanced high frequency field-effect transistors.

4. 18. Effects of impurities on charge transport in graphene field-effect transistors

   Författare :Marlene Bonmann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carrier transport; electron and hole mobility; impurities; traps; graphene; field-effect transistors; microwave devices; saturation velocity; remote phonons;

   Sammanfattning : In order to push the upper frequency limit of high speed electronics further, thereby extending the range of applications, new device technologies and materials are continuously investigated. The 2D material graphene, with its intrinsically extremely high room temperature charge carrier velocity, is regarded as a promising candidate to push the frequency limit even further. LÄS MER

5. 19. Market Structure and Integration - Essays on Trade, Specialisation and Foreign Direct Investment

   Författare :Karin Olofsdotter; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; Economics; Economic Integration; Market Size; Scale Economies; Welfare; Specialisation; Country Capabilities; Trade; Economic Growth; Foreign Direct Investment; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

   Sammanfattning : The study analyses various aspects of international economics related to foreign direct investment, trade and specialisation. These issues are considered in view of the increased internationalisation - through trade and foreign direct investment - in recent decades. Special interest is devoted to the effects of economic integration. LÄS MER

7. 20. Direct Write Technology of SIN Tunnel Junctions for Thermometry and Microwave Devices

   Författare :Ernst Otto; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cryogenic; Cold-Electron Bolometer; direct write technology; SIN tunnel junction;

   Sammanfattning : This thesis concerns development of SIN junction technology for thermometry and microwave detectors, as well as technology of a planar phase switch as a part of integratedmicrowave receiver.Cold-Electron Bolometer (CEB) is a sensitive detector of a microwave radiation, in which SIN tunnel junctions are used for temperature measurement of a nanoscale absorber in thesame way as in SIN thermometers.
