Compound Semiconductor Technology (CST) works in the field of deposition and characterization of compound semiconductors and organic semiconductor materials as well as in the field of electronic and optoelectronic devices. The concrete research goals are energy-efficient components for power electronics, display technology, solid state lighting, optoelectronics and organic / hybrid photovoltaics.
Group III nitrides are wide band-gap semiconductors for high-frequency and power transistors for communications and power electronics. The direct band gap which can be set in the range from 0.8 eV to 6.2 eV makes this material interesting for light emitting and laser diodes as well as solar cells.
In contrast, organic semiconductors are predestined for deposition on large-area and flexible substrates. Electrically and optically active layers therefore find wide application possibilities, especially in consumer electronics, lighting, photovoltaics and displays.
