The idea of supporting the Sustainable Development Goals (SDGs) has inspired researchers around world to explore more environmentally friendly energy generation and production methods, especially those related solar hydrogen energy. Among various available sustainable technologies, photo(electro)catalytic been competitively explored, benefiting from its versatile platform utilize for green prod...

In this paper, a high-performance electro-optical tunable grating-assisted directional coupler (GADC) is proposed and demonstrated experimentally. Our GADC consists of two-mode waveguide (TMW) single-mode (SMW) formed with lithium niobate (LN). By introducing long-period grating into the side-wall TMW to compensate for phase mismatch fundamental modes SMW TMW, two waveguides can be coupled effi...

The injection of positive charge carriers (holes) into a single conjugated polymer chain was observed to be light-assisted. This effect may underlie critical, poorly understood organic electronic device phenomena such as the build-up of functional deeply trapped charge layers in polymer light emitting diodes. The charging/discharging dynamics were investigated indirectly by a variety of single ...
