Atomic and electronic structure of ultra-thin Al/AlOx/Al interfaces
Interfaces between metals based on AlO represent the most popular basis
for Josephson junctions or, more recently, also for junctions exhibiting
substantial tunneling magneto-resistance. We have performed a computational
study of possible local geometric structures of such interfaces at the
ab-initio DFT/GGA level of approximation to complement recent experimental data
on ultra-thin AlO-based interfaces. We present two competing structures
that we characterise with their electronic properties: fragmentation and
interface energies.Comment: Presented at the ECOSS24, submitted to the proceeding - special issue
