    Jin H, Hagen D, Karppinen M. Low-temperature atomic layer deposition of crystalline manganese oxide thin films. Dalton Trans. 2016;45:18737-18741 pubmed
    ..In both cases an appreciably high growth rate of ?1.2 Å per cycle is achieved. The spinel-structured Mn3O4 thin films are shown to be ferrimagnetic with the transition temperature determined to be at ?47 K. ..
  2. Hagen D, Tripathi T, Karppinen M. Atomic layer deposition of nickel-cobalt spinel thin films. Dalton Trans. 2017;46:4796-4805 pubmed publisher
    ..5 was observed. The conformal deposition of dense films on high-aspect-ratio patterns is demonstrated. ..
  3. Ahvenniemi E, Karppinen M. ALD/MLD processes for Mn and Co based hybrid thin films. Dalton Trans. 2016;45:10730-5 pubmed publisher
    ..The films are stable towards humidity and withstand high temperatures up to 300 or 400 °C under an oxidative or a reductive atmosphere. The films are characterized with XRR, AFM, GIXRD, XPS and FTIR techniques. ..
  4. Ahvenniemi E, Karppinen M. Atomic/molecular layer deposition: a direct gas-phase route to crystalline metal-organic framework thin films. Chem Commun (Camb). 2016;52:1139-42 pubmed publisher
    ..The films are grown from two gaseous precursors with a digital atomic/molecular level control for the film thickness under relatively mild conditions in a simple and fast one-step process. ..

  6. Ahvenniemi E, Matvejeff M, Karppinen M. Atomic layer deposition of quaternary oxide (La,Sr)CoO3-δ thin films. Dalton Trans. 2015;44:8001-6 pubmed publisher
    ..The most detailed study was conducted for x = 0.7, i.e. the composition with the highest application potential within the (La1-xSrx)CoO3-δ system. ..
  7. Tanskanen A, Karppinen M. Iron-Terephthalate Coordination Network Thin Films Through In-Situ Atomic/Molecular Layer Deposition. Sci Rep. 2018;8:8976 pubmed publisher
    ..The chemical composition and structure of the films are investigated with GIXRD, XRR, FTIR and XPS. ..
  8. Tanskanen A, Karppinen M. Iron-based inorganic-organic hybrid and superlattice thin films by ALD/MLD. Dalton Trans. 2015;44:19194-9 pubmed publisher
