PFHub: The Phase-Field Community Hub

Daniel Wheeler, Trevor Keller, Jonathan E. Guyer, James A. Warren, Stephen DeWitt, Andrea Jokisaari, Daniel Schwen, Larry Aagesen, Olle Heinonen, Michael Tonks, Peter Voorhees
An online portal provides a valuable space for scientific communities to summarize a shared challenge, collect attempts at a solution, and present a

FiPy: PDEs in Python

Jonathan E. Guyer, Daniel Wheeler, James A. Warren
Partial differential nist-equations (PDEs) are ubiquitous to the mathematical description of physical phenomena. They describe the relationships between

Superfilling When Adsorbed Accelerators Are Mobile

Daniel Josell, Thomas P. Moffat, Daniel Wheeler
Bottom-up superfill during electrodeposition that is used for industrial processing of damascene copper interconnects has also been demonstrated during

FiPy: A Finite Volume PDE Solver Using Python

Daniel Wheeler, Jonathan E. Guyer, James A. Warren
The solution of coupled sets of partial differential nist-equations (PDEs) is ubiquitous in continuum models for phase transformations, such as in phase field

Superconformal Deposition and the CEAC Mechanism

Thomas P. Moffat, Daniel Wheeler, Daniel Josell
The mechanism and modeling of superconformal film growth used in the electrochemical fabrication of 3-D Cu interconnects is briefly reviewed. The central role

Accelerator Aging Effects During Copper Electrodeposition

Thomas P. Moffat, B C. Baker, Daniel Wheeler, Daniel Josell
Slow sweep rate voltammetric analysis of the Cu/Cu(II) deposition reaction is shown to be an effective tool for examining aging effects associated with thiol
