    Structural and chemical characterization data for Ir and Ru metal/metal-oxide thin films showing strain dependence of metal oxidation
    (2023-04-05) Nair, Sreejith T; Yang, Zhifei; Lee, Dooyong; Guo, Silu; Sadowski, Jerzy T; Johnson, Spencer; Saboor, Abdul; Li, Yan; Zhou, Hua; Comes, Ryan B; Jin, Wencan; Mkhoyan, Andre K; Janotti, Anderson; Jalan, Bharat; nair0074@umn.edu; Nair, Sreejith T; University of Minnesota Jalan MBE Lab
    In this work, the authors uncover a previously unexplored effect of substrate imposed epitaxial strain on the formation energy of a crystalline epitaxial metal oxide thin film, thereby revealing an additional tuning knob to engineer synthesis of oxide thin films of hard-to-oxidize metals.

    X-ray Diffraction and Atomic Force Microscopy of RuO2 thin films
    (2022-08-18) Nunn, William; Manjeshwar, Anusha K; Nair, Sreejith; Jalan, Bharat; bjalan@umn.edu; Jalan, Bharat; University of Minnesota Jalan MBE Lab
    X-ray Diffraction data of the RuO2 samples were obtained to assess the crystallinity and epitaxial nature of the thin films grown on different substrates. Atomic Force Microscopy was used to determine the surface morphology changes as a function of thickness and epitaxial strain and correlate it with the observed oxygen evolution activity.
