Hot stuff: schematic of the bolometer showing the graphene sheet in blue. (Courtesy: MIT) A new graphene-based bolometer has been created by Dmitri Efetov and colleagues at the Massachusetts Institute ...

Researchers in the US have unveiled a new way of using graphene to detect light. The team’s graphene-based bolometer works in the infrared and although the first version of the device must be chilled ...

Devices such as digital cameras electronically measure levels of high-energy light, and that's good enough for most of us. Now, however, scientists have developed a mechanical alternative that works ...

The findings, published in the journal Nature Nanotechnology ("Fast thermal relaxation in cavity-coupled graphene bolometers with a Johnson noise read-out"), could help pave the way toward new kinds ...

Researchers have developed a better bolometer, a device for measuring electromagnetic radiation. The new technology is faster, simpler, and covers more wavelengths. Bolometers, devices that monitor ...

Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures – a scale trillion times lower than ...

Scientists have hailed a new quantum computing breakthrough that could bring the revolutionary technology into the real world. The discovery could fundamentally change how quantum computers are able ...
