    Sammanfattning : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.

    Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

    Sammanfattning : First principle electronic structure theory is used to describe the effect of crystal binding on radiation detectors, electron transport properties, and structural damage induced by intense irradiation. A large database containing general electronic structure results to which data mining algorithms can be applied in the search for new functional materials, a case study is presented for scintillator detector materials.
