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.
Photoluminescence and photocurrent measurements indicate that MoSe2/WS2 hetero-bilayers can be switched from type-I to type-II band alignment by applying a vertical electric field.
The authors present nonvolatile optical phase shift induced by ferroelectric hafnium zirconium oxide deposited on a SiN waveguide. This finding paves the way for largescale programmable photonic circuits for communication, computing, and sensing.
A molecular design strategy for reducing the vibration-induced non-radiative losses in emissive organic semiconductors is realized by decoupling excitons from high-frequency vibrations.
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.
