Rapid journey through a crystal lattice
Munich, Germany (SPX) Jan 15, 2015
The time frames, in which electrons travel within atoms, are unfathomably short. For example, electrons excited by light change their quantum-mechanical location within mere attoseconds – an attosecond corresponds to a billionth of a billionth of a second.
But how fast do electrons whiz across distances corresponding to the diameter of individual atomic layers? Such distances are but a few —> Read More Here
