Crystal plasticity finite element simulation of lattice rotation and x-ray diffraction during laser shock-compression of Tantalum
P. Avraam, D. McGonegle, P. G. Heighway +7
Wehrenberg et. al. [Nature 550 496 (2017)] used ultrafast in situ x-ray diffraction at the LCLS x-ray free-electron laser facility to measure large lattice rotations resulting from…
Fermi level pinning can determine polarity in semiconductor nanorods
Philip W. Avraam, Nicholas D. M. Hine, Paul Tangney +1
First-principles calculations of polar semiconductor nanorods reveal that their dipole moments are strongly influenced by Fermi level pinning. The Fermi level for an isolated nanor…
Factors influencing the distribution of charge in polar nanocrystals
Philip W. Avraam, Nicholas D. M. Hine, Paul Tangney +1
We perform first-principles calculations of wurtzite GaAs nanorods to explore the factors determining charge distributions in polar nanostructures. We show that both the direction…
