Nanostructured solids – From nano-glasses to quantum transistors Shear band formation Although there is a broad consensus that STZs are the basic units of plastic deformation in metallic glasses and that yielding involves a critical number of STZs, it is still an open question how the activation ...
We conducted a large-scale density-functional theory study on the influence of the exchange-correlation functional in the calculation of electronic band gaps of solids. First, we use the large materials data set that we have recently proposed to benchmark 21 different functionals, with a particular...

However, in solids, these energy levels combine to form bands. Those electrons that are used to bind the atoms are present in the valence energy band, whereas the leftover electrons are able to move freely around. For many materials, there is an energy gap between the two bands. The ...
