Lateral current spreading is experimentally and theoretically investigated in stripe laser diodes. The influence of current spreading length to threshold current density is quantitatively analyzed.

A beauty editor's honest review of the Ulike LED mask, plus notes on how it works, who it's best for, and if it's worth the ...

A novel metamaterial emits significantly more heat than it absorbs under a magnetic field, breaking Kirchhoff’s law.

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

This paper presents the electric field distribution and current emission in a vacuum nano-diode. The electric field is calculated exactly inside a finite vacuum cathode-anode (A-K) gap with a single ...

Recent alleged details on the power of the Switch 2 weren't the first rumors to spread about Nintendo’s new console. Other allegedly leaked details have suggested that the device will feature ...

Cultural differences: Some Redditors suggest that TSMC’s work ethic and management style give them an edge. There’s a ...
