Photoelectrode that can harvest 85 percent of visible light

Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.

A laser that tracks like a hound

University of Adelaide researchers have created a laser that can "smell" different gases within a sample.

Unconventional solution process for 2-D heterostructure

Solution-processed transitional metal chalcogenide (TMD) nanosheets exhibit limited light absorption and low quantum efficiencies because of their atomic-scale thicknesses and large specific surface area accompanied with ...

Photoexcited graphene puzzle solved

Light detection and control lies at the heart of many modern device applications, such as smartphone cameras. Using graphene as a light-sensitive material for light detectors can offer significant improvements with respect ...

Fix for synchrotron research flaw could improve results

University of Saskatchewan researchers have found that chemicals commonly used to protect samples in synchrotron experiments actually help to damage those samples, potentially misleading scientists around the world.

Turning graphene into light nanosensors

Graphene has many properties; it is e.g. an extremely good conductor. But it does not absorb light very well. To remedy this limiting aspect of what is an otherwise amazing material, physicists resort to embedding a sheet ...

Researchers discover how colliding oxygen molecules absorb light

Scientists at Radboud University have managed to do what had never been tried before: accurately describe how colliding oxygen molecules absorb light. Our atmosphere consists of approximately 20 percent oxygen molecules, ...
