Every time a smartphone snaps a photo, millions of tiny light detectors capture the scene and then ferry all that raw data across the chip to a separate processor for storage and number-crunching.

P-n diodes are two-terminal devices that consist of two types of semiconductor materials (i.e., a p-type and an n-type ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

In a study published in Nature Electronics, a research team led by Prof. SUN Haiding from the University of Science and Technology of China of the Chinese Academy of Sciences, along with the ...

PN junction diodes are the underpinning of modern optoelectronic systems. But, typically, they perform only a single task. To ...

Scientists have reviewed the superconducting diode effect, a quantum effect enabling dissipationless supercurrent to flow in only one direction. The SDE provides new functionalities for ...

In an optical diode, the light input in one direction is transmitted while the light input in the opposite direction is blocked. The new optical diode is made from parity-time (PT) symmetric ...
