03 Mar 2015  Online Presentations  Contributor(s): Manijeh Razeghi
Nature offers us different kinds of atoms. But it takes human intelligence to put different atoms together in an elegant way in order to realize manmade structures that is lacking in nature. This is especially true in IIIV semiconductor material systems. Guided by highly accurate atomic band...

Symmetry, Dimension, and Spin: Understanding transport in 2D 'phosphorene'
03 Mar 2015  Online Presentations  Contributor(s): Ian Appelbaum
Despite its low atomic number and inversion symmetry, recent electronic measurements demonstrate that (groupIV) graphene has a greatly disappointing spin lifetime, corroborated by theory showing strong spinflip scattering by flexural (outofplane) phonons. There exists a class of...
