Brief description:
Imaging sensors find widespread application in everyday life and therefore represent a major economic factor, with an annual turnover of several billion US dollars. At the Institute of Applied Physics of Technische Universität Dresden, within the research group of Prof. Karl Leo, novel organic phototransistors have recently been developed that surpass the sensitivity and detectivity of established detector technologies while offering a range of additional advantages.
The key innovation is a new organic transistor with a vertical device architecture that detects an optical signal and amplifies it directly at the point of detection, analogous to commercial CMOS technology. Furthermore, these devices enable the temporary storage of charge carriers and feature a small lateral footprint, making them highly promising for application in matrix sensors.
Within the OPTICUS validation project, this novel technology is being evaluated and further developed with regard to commercial applications. The main objectives of the project are to extend the spectral photoresponse of the phototransistors into the infrared spectral range and to develop a concept for their implementation in matrix sensors in combination with a readout integrated circuit.
