21. Electrochemical and electronic devices based on low bandgap polymers
Sammanfattning : The research field of the organic electronics includes light emitting diodes (OLEDs), field-effect transistors (OFETs), polymer photovoltaic cells (PVCs), polymer lasers and electrochemical devices. Recently, organic materials are envisaged for spintronics. LÄS MER
22. Organic Photodiodes : Optical, electric, and morphological aspects of polymer based devices
Sammanfattning : The use of semiconducting organic materials as the active layer in optoelectronic devices offers some advantages in processing and new possibilities of device fabrication such as large-area devices. The mechanism of charge generation upon light absorption in organic materials differs from that in inorganic semiconductors. LÄS MER
23. Surfaces and interfaces of low dimensional III-V semiconductor devices
Sammanfattning : The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational units.
