Broadband wavelength-selective isotype heterojunction n+-ZnO/n-Si photodetector with variable polarity
Georgios Chatzigiannakis, Angelina Jaros, Renaud Leturcq +4
An isotype heterojunction n+-ZnO/n-Si photodetector is developed, demonstrating wavelength-selective or broadband operation, depending on the applied bias voltage. Additionally, at…
Laser-microstructured ZnO/p-Si photodetector with enhanced and broadband responsivity across the UV-Vis-NIR
Georgios Chatzigiannakis, Angelina Jaros, Renaud Leturcq +4
We develop ZnO/p-Si photodetectors by atomic layer deposition (ALD) of ZnO thin films on laser-microstructured silicon and we investigate their electrical and optical behavior, dem…
Electron tunneling from colloidal CdSe quantum dots to ZnO nanowires studied by time-resolved luminescence and photoconductivity experiments
Stephanie Bley, Michael Diez, Friederike Albrecht +6
CdSe quantum dots (QDs) with different organic linker molecules are attached to ZnO nanowires (NWs) to study the luminescence dynamics and the electron tunneling from the QDs to th…
Coherent Propagation of Polaritons in Semiconductor Heterostructures: Nonlinear Pulse Transmission in Theory and Experiment
S. Schumacher, G. Czycholl, F. Jahnke +7
The influence of coherent optical nonlinearities on polariton propagation effects is studied within a theory-experiment comparison. A novel approach that combines a microscopic tre…
