11. Chemical Doping of Conjugated Polymers for Thermoelectric Applications
Sammanfattning : The ongoing development of interconnected and wearable small devices, which together make up the so-called Internet of Things, is driving a rising need for autonomous and on-site energy supplies. Heat, an abundant and often wasted energy source, can be harnessed through thermoelectric generators that can directly convert heat into electricity. LÄS MER
12. Molecular Electronics - Modeling, Devices and Architecture
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.

13. Synthesis of Novel Fluorine-Free Salts for Battery Electrolytes
Sammanfattning : Nowadays lithium-ion batteries (LIBs) are the dominant power sources of portable electronic devices such as mobile phones, laptops and cameras. Although recently their applications have extended to areas of electromobility and hybridization of vehicle, cost and safety issues remain as big obstacles for a smoother implementation. LÄS MER
14. Components of smart windows : Investigations of electrochromic films, transparent counter electrodes and sputtering techniques
Sammanfattning : In smart windows, the transmittance of visible and near infrared radiation can be reversibly and persistently modulatcd by an applied voltage pulse (~2 V). The micrometer-thick multi-layer structure contains two electrodes capable of charge insertion. One of these electrodes must be electrochromic; usually it consists of tungsten oxide. LÄS MER
15. Preparation and characterization of sputtered metal oxides and nitrides for optical applications
Sammanfattning : Sputter deposited metal oxide and nitride thin films have been studied for energy-efficient window applications. Coatings, for both static and dynamic control of radiative heat transfer through windows, were optically characterized. As metal base in static solar selective coatings, semi-transparent TiN and ZrN films have been investigated. LÄS MER
