16. Essays on the Evaluation of Public Policies
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).

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

18. Effects of impurities on charge transport in graphene field-effect transistors
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
19. Market Structure and Integration - Essays on Trade, Specialisation and Foreign Direct Investment
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
20. Direct Write Technology of SIN Tunnel Junctions for Thermometry and Microwave Devices
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.
