Photon-induced tunneling in graphene-boron nitride-graphene heterostructures
… and optical properties. In this work, we present optoelectronic measurements performed on ultrathin graphene-boron nitride-graphene heterostructures. Scanning photocurrent spectroscopy allows us to explore the tunneling behavior of these devices as a function of both photon energy and bias …

Flaw-limited transport in germanium-on-silicon photodiodes
… photodiode performance is then quantified by optoelectronic measurements and analyzed in the context of the flaw limited transport. Device applicability for integration with an existing photonic sampling system is analyzed and intersymbol interference, noise and linearity metrics are measured …

Optoelectronic characterization of wide-bandgap (AgCu)(InGa)Se 2 thin-film polycrystalline solar cells including the role of the intrinsic zinc oxide layer
… then fabricated and characterized by a number of optoelectronic techniques. Thin film CIGS has received a lot of attention, for its use as an absorber layer for thin film solar cells. However, the addition of Silver (Ag) to the CIGS alloy system increases the band gap as indicated from optical …

Correlation between dynamic parameters and device performance of organic solar cells
… conditions. One new approach is to perform TDCF measurements with increasing delay between generation and extraction of charges. Thus, TDCF was used for the first time to measure charge carrier generation, recombination and transport with the same experimental setup. This excludes experimental …
