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…
Effect of realistic metal electronic structure on the lower limit of contact resistivity of epitaxial metal-semiconductor contacts
Ganesh Hegde, R. Chris Bowen
The effect of realistic metal electronic structure on the lower limit of resistivity in [100] oriented n-Si is investigated using full band Density Functional Theory and Semi-Empir…
