The idea is to replace night vision goggles, which are often heavy and cumbersome. Until recently, the main candidate was gallium arsenide.

This development could allow for more accessible and wearable night-vision glasses, ... This new research improves upon previous research which utilized gallium arsenide as a metasurface.

The nanocrystals, which are made of aluminium, gallium and arsenide, are each 500 times narrower than a human hair and can be applied to glass as ultra-thin, lightweight films.

Nanotechnology may result in cheaper night vision goggles. ... Each dot has a core of indium arsenide surrounded by gallium arsenide and an indium-gallium arsenide alloy.

A pair of night-vision glasses would change the way we navigate the late hours, from driving to walking home in the dark. This vision is nearer to reality, as researchers simplify how light is ...

Consumer night vision glasses that allow the user to see the visible and infrared spectrum at the same time could result in safer driving in the ... which featured a gallium arsenide metasurface.

Two obscure yet crucial metals, gallium and germanium, are the latest pawns in the escalating US-China trade war. On Dec. 3, China announced an export ban on both metals to the US in a tit-for-tat ...

Small amounts of primary gallium - around 10 metric tons in 2021 - are produced by Japan, Russia and South Korea, according to USGS, while additional amounts also come from recycled material.

China said on Monday it will impose export restrictions from Aug. 1 on some gallium and germanium products, metals used in computer chips and other products, to protect national security interests.

Gallium arsenide - a compound of gallium and arsenic - is used in high-frequency computer chips, ... It is also used in vision goggles which are "key to the military," Mr Hamilton said.
