An MsFEM approach enriched using Legendre polynomials
Frederic Legoll, Pierre-Loik Rothe, Claude Le Bris +1
We consider a variant of the conventional MsFEM approach with enrichments based on Legendre polynomials, both in the bulk of mesh elements and on their interfaces. A convergence an…
Nested Dissection Solver for Transport in 3D Nano-Electronic Devices
Y. Zhao, U. Hetmaniuk, S. R. Patil +2
The Hierarchical Schur Complement method (HSC), and the HSC-extension, have significantly accelerated the evaluation of the retarded Green's function, particularly the lesser Green…
Negative Differential Resistance in Boron Nitride Graphene Heterostructures: Physical Mechanisms and Size Scaling Analysis
Y. Zhao, Z. Wan, X. Xu +3
Hexagonal boron nitride (hBN) is drawing increasing attention as an insulator and substrate material to develop next generation graphene-based electronic devices. In this paper, we…
A Nested Dissection Approach to Modeling Transport in Nanodevices: Algorithms and Applications
U. Hetmaniuk, Y. Zhao, M. P. Anantram
Modeling nanoscale devices quantum mechanically is a computationally challenging problem where new methods to solve the underlying equations are in a dire need. In this paper, we p…
