Machine-learned approximations to Density Functional Theory Hamiltonians

Ganesh Hegde, R. Chris Bowen

Large scale Density Functional Theory (DFT) based electronic structure calculations are highly time consuming and scale poorly with system size. While semi-empirical approximations…

Lower limits of line resistance in nanocrystalline Back End of Line Cu interconnects

Ganesh Hegde, R. Chris Bowen, Mark S. Rodder

The strong non-linear increase in Cu interconnect line resistance with a decrease in linewidth presents a significant obstacle to their continued downscaling. In this letter we use…

On the feasibility of ab initio electronic structure calculations for Cu using a single s orbital basis

Ganesh Hegde, R. Chris Bowen

The accuracy of a single s-orbital representation of Cu towards enabling multi-thousand atom ab initio calculations of electronic structure is evaluated in this work. If an electro…
