Bolometers, devices that monitor electromagnetic radiation through heating of an absorbing material, are used by astronomers and homeowners alike. But most such devices have limited bandwidth and must ...

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride ...

Cool idea: images of the bolometer on a silicon chip. (Courtesy: Jean-Philippe Girard/Aalto University) A new type of bolometer that covers a broad range of microwave frequencies has been created by ...

Chip-level future: an artist’s impression of how microscopic bolometers (in the chip on the right) could sense very weak radiation emitted from qubits (in the chip on the left). (Courtesy: Aleksandr ...

Bolometers are a powerful means of detecting light. Emerging applications demand that bolometers work at room temperature, while maintaining high speed and sensitivity, properties which are inherently ...

The nanoscale radiation detector is a hundred times faster than its predecessors, and can function without interruption. Researchers from Aalto University and VTT Technical Research Centre of Finland ...

One of many astonishing properties of graphene is its weak electron-phonon (e-p) coupling. In normal conductor, e-p scattering quickly dominates as the temperature increases, resulting in a ...

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or ...

I don’t know about you, but this thing doesn’t seem like a scintillating bolometer to me. At all. Eduardo Abancens—a University of Zaragoza’s physicist—says it’s a dark matter detector. One that looks ...

WASHINGTON, D.C., February 6, 2018 -- Graphene is a remarkable material: light, strong, transparent and electrically conductive. It can also convert heat to electricity. Researchers have recently ...

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 ...
