Inorganic nanoparticles are increasingly used in electronic components due to their easily size-controllable properties. The combination with organic semiconductors provides hybrid materials with unique functionalities different from the individual systems.
In my work, PbS nanoparticles in combination with various organic semiconductors are investigated for their applicability as active materials in optoelectronic devices. The material characteristics are examined by means of transport measurements in a FET setup in the temperature range of 8.5 K – 300 K, wherein a sample can get probed both in the dark and under laser illumination. Here, the switching time of the photoconductive material (‘off‘ state = dark current, ’on‘ state = current under illumination) is particularly interesting, as it limits the speed of data processing in optical switches when feeding a computer with the optical signals from glass fibres.
Besides this, further possible techniques to characterize the materials are UV/Vis/NIR- and FTIR-spectroscopy, and XPS (in cooperation with the Chassé group).
