A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry
A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical ...
Researchers at the University of Hong Kong have demonstrated a purely physical method to change gallium nitride’s light emission from ultraviolet to blue by mechanically stretching it. The technique ...
Microfabrication of bulk GaN crystal into single crystalline GaN microbridges. An optical photograph showing the bulk GaN ...
Electric vehicles, converters for charging infrastructure, energy storage systems, solar and wind power plants or new types of heat pumps — key technologies for the energy transition rely on ...
The power semiconductor evolution started with germanium and selenium devices that succumbed to silicon types around the 1950s. Broader silicon usage stemmed from its improved physical properties ...
Gallium nitride (GaN) is a binary III/V semiconductor seen as a potential successor to silicon. GaN has a wider bandgap than silicon, meaning it can maintain higher voltages in electronic devices. 1 ...
