Recently, the research group of Prof. Jun He and Associate Prof. Yingwei Wang from the School of Physics, Central South University observed the polaronic state assisted sub-bandgap saturable ...

New technologies aim to produce high-purity synthetic crystals that become excellent semiconductors when doped with impurities as electron donors or acceptors of other elements. Researchers have now ...

Organic semiconductors are materials that find applications in various electronic devices. Exciton binding energy is an important attribute that influences the behavior of these materials. Now, ...

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 ...

Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny and interact strongly with each other, but move slowly. Together, the two ...

Scientists in the United States have designed a microwire solar cell that could reportedly enable the coupling of singlet fission with silicon. Key to their achievement was an interface that transfers ...

The iridescent blue of butterfly wings has inspired researchers to find a solution to a challenge previously considered insurmountable - dynamically tuning advanced optical processes at visible ...

Kyoto, Japan -- Besides being "a girl's best friend," diamonds have broad industrial applications, such as in solid-state electronics. New technologies aim to produce high-purity synthetic crystals ...
