Using a new method, physicists found a way to 'catapult' electrons across solar materials in quadrillionths of a second.

If you think “instantaneous” happens in a second, you should meet Haiwang Yong. An assistant professor of chemistry at the ...

New measurements in germanium reveal how excited electrons drive lattice vibrations that govern energy flow and heating in semiconductors. (Nanowerk News) Whether in a smartphone or laptop, ...

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is ...

Ultrafast spectroscopy today spans a broad range of applications, including photo physics and photochemistry of organic and inorganic materials, light-harvesting and energy-conversion processes, etc.

Scientists successfully visualized the ultrafast dynamics of quasi-particles known as excitons, which are generated in carbon nanotubes upon light excitation. This was achieved with spatial and ...

Halide perovskites—already a focus of major research into efficient, low-cost solar cells—have been shown to handle light faster than most semiconductors on the market. A new paper, published in ...

Virtually every scientific field has made strides by harnessing light to study the properties of substances. This technique, called spectroscopy, has countless research applications, and innovations ...

It took three years for researchers Grazia Raciti, Begoña Abad Mayor, and Ilaria Zardo (from left to right) to develop and characterize the complex setup – only then were the now-published ...
