Optoelectronic devices and components are those electronic devices that operate on both light and electrical currents. This can include electrically driven light sources such as laser diodes and light-emitting diodes, components for converting light to an electrical current such as solar and photovoltaic cells and devices that can electronically control the propagation of light.
In this work, a nanoscale light-emitting diode with memory-electroluminescence is demonstrated, which is used for mimicking the generation of multiple action-potentials and their combinations in bio-inspired afferent nerves.
By integrating a metal‒oxide‒semiconductor capacitor into a two-terminal diode, a multifunctional single device can be created that operates as a tunable light-emitting diode with a built-in bias tee circuit and a detector with a reconfigurable optoelectronic logic function.
The full potential of photoelectric devices can possibly be maximized through pyroelectricity for power generation beyond thermodynamic limit. Here, authors report photovoltaic heterostructure device with pyroelectric absorber, achieving 2.5 times more output power due to long-range electric field.
The integration of transition metal thio/selenophosphates (TPS) like CuInPS and CuCrPS onto Silicon Photonics marks a significant advancement in optical devices. This innovation provides precise control over refractive index, minimizes optical losses, enhances modulation efficiency, and reduces the footprint for next-generation optoelectronics.
Researchers demonstrate a germanium/silicon avalanche photodiode gain–bandwidth product over 1 THz operating at 1,550 nm wavelength. The findings have implications for future high-speed optoelectronic devices in next-generation optical interconnects.
Dual-channel mechano-phosphorescence, characterized by dual emission and ultralong organic phosphorescence, was achieved by strengthening the intra- and intermolecular interactions in the highly twisted structures to realize a combined locking effect.
Electrical excitation of a perovskite light-emitting diode is shown to contribute to optical gain, a milestone on the path towards a non-epitaxial laser diode.
New conductive and perovskite inks enable hand-drawing of optoelectronic devices with a ballpoint pen on a variety of daily substrates, including paper, textiles and other irregular surfaces.
