Graphene could yield cheaper optical chips

Graphene—which consists of atom-thick sheets of carbon atoms arranged hexagonally—is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it's also the strongest material known to man.

Graphene photodetector integrated into computer chip

The novel material graphene and its technological applications are studied at the Vienna University of Technology. Now scientists succeeded in combining graphene light detectors with semiconductor chips.

Research boosts understanding of nano-carbon in photodetectors

As modern electronic devices get ever smaller, the age of silicon transistors is going by the wayside. Tomorrow's electronics—such as photovoltaic panels, transparent conductors, capacitors, transistors and photodetectors—are ...

Photons a la Mode: Studying light pulses by counting photons

( —The photodetectors in Alan Migdall's lab often see no light at all, and that's a good thing since he and his JQI colleagues perform physics experiments that require very little light, the better to study subtle ...

Large Area Picosecond Photodetectors push timing envelope

The Large Area Picosecond Photodetector (LAPPD) collaboration has developed big detectors that push the timing envelope, measuring the speed of particles with a precision down to trillionths of a second.

Auto lubricant could rev up medical imaging

Engineers at the University of California, Berkeley, have built a device that could speed up medical imaging without breaking the bank. The key ingredient? An engine lubricant called molybdenum disulfide, or MoS2, which has ...

Gold nanoparticles improve photodetector performance

The mineral molybdenum disulfide (MoS2), which, when solid, behaves in many ways like grease, has semiconducting properties that make it a promising alternative to silicon or graphene in electronic devices. It also strongly ...

Team uses carbon nanotubes for polarized-light detection

Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of ...
