Making new materials an atomic layer at a time

Researchers have shown the ability to grow high quality, single-layer materials one on top of the other using chemical vapor deposition. This highly scalable technique, often used in the semiconductor industry, can produce new materials with unique properties that could be applied to solar cells, ultracapacitors for energy storage, or advanced transistors for energy efficient electronics, among many other applications.

Excitons observed in action for the first time

A quasiparticle called an exciton - responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits - has been understood theoretically for decades. But exciton movement within materials has never been directly observed.

Perfect nanospheres using ultrashort laser pulses

The Nanophotonics Group of the Laser Zentrum Hannover has developed a method to print nanoparticles made of different materials with controlled, reproducible sizes and to precisely deposit these particles on a receiver substrate. As a result, for the first time, the scientists succeeded in generating and positioning perfectly round silicon nanoparticles with a diameter of 165 nm.
