New type of bolometer detector for far-infrared telescopes

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 bolometers are used as ...

Is Webb at its final temperature?

The Mid-Infrared Instrument (MIRI) on NASA's James Webb Space Telescope is now cooled by a gaseous helium cryocooler to under 7 Kelvin. With the cooler in its final state, the Webb team is operating the MIRI instrument this ...

Engineering 2D semiconductors with built-in memory functions

A team of researchers at The University of Manchester's National Graphene Institute (NGI) and the National Physical Laboratory (NPL) has demonstrated that slightly twisted 2D transition metal dichalcogenides (TMDs) display ...
