source: ETH ZurichRare earth metals are not as rare as their name suggests. However, they are indispensable for the modern economy. After all, these 17 metals are essential raw materials for digitalization and the energy transition.They are found in smartphones, computers, screens and batteries—without them, no electric motor would run and no wind turbine would turn. Because Europe is almost entirely dependent on imports from China, these raw materials are considered to be critical.However, rare earth metals are also critical because of their extraction. They always occur in compound form in n...

source:Tech XploreElectronics engineers and materials scientists have been trying to identify materials that could help to boost the performance of electronics further, overcoming the inherent limitations of silicon-based transistors. Two-dimensional (2D) semiconductors have advantageous properties that make them promising candidates for the development of better performing transistors.Most notably, 2D semiconductors are atomically thick and exhibit high carrier mobilities, two qualities that could improve the electrostatic control and ON-state performances of short-channel field-effect transi...
