A new theory for semiconductors made of nanocrystals

Researchers at ETH have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or ...

Formation of honeycomb nanostructures finally explained

A few years ago, a promising new type of nanomaterial was observed experimentally, combining the virtues of semiconductors with those of graphene. The material is formed by nanocrystals that spontaneously assemble into a ...

Extremely bright and fast light emission

An international team of researchers from ETH Zurich, IBM Research Zurich, Empa and four American research institutions have found the explanation for why a class of nanocrystals that has been intensively studied in recent ...

Technology increases microfluidic research data output 100-fold

Researchers have developed a technique that allows users to collect 100 times more spectrographic information per day from microfluidic devices, as compared to the previous industry standard. The novel technology has already ...

Molecular-like photochemistry from semiconductor nanocrystals

Researchers from North Carolina State University have demonstrated the transfer of triplet exciton energy from semiconductor nanocrystals to surface-bound molecular acceptors, extending the lifetime of the originally prepared ...

Molecular shuttle speeds up hydrogen production

An LMU team affiliated with the Nanosystems Initiative Munich (NIM) has achieved a breakthrough in light-driven generation of hydrogen with semiconductor nanocrystals by using a novel molecular shuttle to enhance charge-carrier ...

Putting more science into the art of making nanocrystals

Preparing semiconductor quantum dots is sometimes more of a black art than a science. That presents an obstacle to further progress in, for example, creating better solar cells or lighting devices, where quantum dots offer ...
