The smart healthcare approach requires continuous monitoring of the individual’s specific health parameters to enable disease diagnostics and treatment at early stages. From that viewpoint, wearable electronics, especially electronic skin...
In this work, we studied the impact of Pb-free perovskite compositions on various properties including crystal structure, carrier mobility and lifetime, photoresponse in lateral devices, and photostability. We focused on...
The recent discovery of photovoltaic (PV) effect in indium (I) iodide thin films have attracted considerable attention, as this material can be a feasible environment-friendly alternative to the conventional lead...
Rare earth metal oxides (REOs) represent promising gate
dielectric
materials for field-effect transistors due to their high dielectric
constants required for suppressing leakage currents in devices. In
this paper, we present an approach to deposition of uniform REO gate
dielectric coatings by oxidation of thin rare earth metal films in
air at relatively low temperatures (100–250 °C). The proposed
methodology was extensively explored in organic field-effect transistors
(OFETs) using five benchmark organic semiconductors and six REOs as
gate dielectrics. It was shown that OFETs with the REO gate dielectrics
deliver on average considerably better characteristics compared to
the reference devices using electrochemically grown aluminum oxide
dielectric (AlOx). OFETs on a flexible plastic substrate
were demonstrated, which makes this approach very attractive for developing
flexible and wearable electronic devices with improved performance.
New BODIPY-coumarin dye was synthesized, characterized, and utilized as a light-sensitive component in optically programmed OFET-based memory cells and photodetectors. The designed photoswitchable OFETs assembled with both n-type (fullerene C60)...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
