Researchers succeeded in experimentally demonstrating that electron mobility in nanowires is remarkably enhanced when the shell places the wire core under tensile strain. This phenomenon offers novel opportunities for the development of ultrafast transistors.
When two or more 2D materials are placed on top of each other their properties change and a material with novel hybrid properties emerges. These materials are called van der Waals heterostructures. By stacking free-standing membranes under observation in an electron microscope, researchers have demonstrated almost arbitrary 3D structures by stacking atomically thin materials, similar to a 3D printing process, where each atomic layer can be chosen from the vast library of available 2D ...
