Abstract

Highlights: [•] Interface barriers for electrons at Al2O3/metal interfaces can be controlled by liners. [•] Tantalum and titanium liners allow for >1eV barrier lowering at Cu/Al2O3 interface. [•] Application of Hf liner is hindered by oxygen scavenging from Al2O3. [Copyright &y& Elsevier]
