The Role of Damage in Fracture Dynamics

A propagating crack tip in a medium poses immense intellectual challenges. Despite the apparent simplicity by which the tip moves, the underlying mechanisms are not at all trivial. In fact only the simplest configurations with a moving crack tip have to t his date been solved. An important aspect...

Transport of spin and charge in semiconductors

Et elektron har et indre magnetisk moment, et "spinn". Spinnet angir en retning og er ikke bare en tallverdi som elektronets elektriske ladning. I normale metaller er det like mange elektroner med spinn i en bestemt retning som i den motsatte. Elektronets spinn har i disse systemene derfor liten...
