A Mixed-Precision Model for Matrix-Splitting Methods
Neil Lindquist, David Appelhans, Chales W. Jackson +1
The performance of stationary iterative methods is memory-bound, due to the low arithmetic intensity. So, we propose a mixed-precision technique to reduce the amount of data moveme…
Embedded Ribbons of Graphene Allotropes: An Extended Defect Perspective
David J. Appelhans, Lincoln D. Carr, Mark T. Lusk
Four fundamental dimer manipulations can be used to produce a variety of localized and extended defect structures in graphene. Two-dimensional templates result in graphene allotrop…
A Two-Dimensional Carbon Semiconductor
David J. Appelhans, Zhibin Lin, Mark T. Lusk
We show that patterned defects can be used to disrupt the sub-lattice symmetry of graphene so as to open up a band gap. This way of modifying graphene's electronic structure does n…
