Broad spectrum: Novel hybrid material proves an efficient photodetector

Phys.orgĀ  April 9, 2020
The MOF compound developed by researchers in Germany comprises an organic material integrated with iron ions. The MOF forms superimposed layers with semiconducting properties, which makes it potentially interesting for optoelectronic applications. They found that the light sensitivity was dependent on temperature and wavelength from 400 to 1,575 nanometers. The spectrum of radiation goes from ultraviolet to near infrared. As the bandgap in the material is very small, only very little light energy is required to induce the electricity. The performance of the detector can be improved by cooling the detector down to lower temperatures and optimizing the component configuration to produce more reliable contacts. This work demonstrates the feasibility of integrating conjugated MOFs as an active element into broadband photodetectors…read more. Open Access TECHNICAL ARTICLE
