One thousand billion operations per second - this peak value is achieved by semiconductor nano-lasers developed by physicist at the University of Jena together with their colleagues from Imperial College London.
Reflection zone plates enable lighter elements in material samples will be efficiently and precisely detected using scanning electron microscopy by providing high resolution in the range of 50-1120 eV.
Researchers found that by adding a specific atomic thin film layer to a transistor, the layer acted as a filter for the energy that passed through it at room temperature. The signal that resulted from the device was six to seven times steeper than that of traditional devices. Steep devices use less voltage but still have a strong signal.
A new method developed for studying battery failures points to the potential next step in extending lithium ion battery lifetime and capacity, opening a path to wider use of these batteries in conjunction with renewable energy sources.
Electricity and magnetism rule our digital world. Semiconductors process electrical information, while magnetic materials enable long-term data storage. A research team has discovered a way to fuse these two distinct properties in a single material, paving the way for new ultrahigh density storage and computing architectures.
The various patterns that atoms of a solid material can adopt, called crystal structures, can have a huge impact on its properties. Being able to accurately predict the most stable crystal structure for a material has been a longstanding challenge for scientists. Researchers calculated the lattice energy of benzene, a simple yet important molecule in pharmaceutical and energy research, to sub-kilojoule per mole accuracy - a level of certainty that allows polymorphism to be resolved.
Gallium arsenide a semiconductor composed of gallium and arsenic is well known to have properties that promise practical applications. In the form of nanowires it has particular potential for use in solar cell manufacture and optoelectronics in many of the same applications that silicon is commonly used. But its natural semiconducting ability requires tuning to make it more desirable for use in manufacturing. New work offers a novel approach to such tuning.
Semiconducting polymers can be used, for example, for the absorption of sun light in solar cells. By incorporating organic tin into the plastic, light can be absorbed over a wide range of the solar spectrum.
NIST recently issued Reference Material (RM) 8027, the smallest known reference material ever created for validating measurements of these man-made, ultrafine particles between 1 and 100 nanometers in size.
