| | Inkjet-printed photodetectors operating at wavelengths up to 3 μm
were made using HgTe nanocrystals. Detectors operate in a spectral region of particular importance for biological applications, remote sensing and
night-vision imaging. A room temperature detectivity of D* = 3.2 × 1010 cm Hz1/2W–1 close to the important telecommunication wavelength region was observed.
This work was performed by Prof. W. Heiss, Dr. M. Böberl, M. V. Kovalenko of the Institute for Semiconductor and Solid State Physics, University Linz together with Dr. S. Gamerith, Prof. E. J. W. List from the Christian Doppler Laboratory for Advanced Functional Materials and the Institute of Solid State Physics, TU Graz.
