    • Density functional and classical simulations of liquid and glassy selenium 

      Kalikka, Janne; Akola, J.; Jones, R. O.; Schober, H.R. (Peer reviewed; Journal article, 2020)
      Molecular dynamics simulations of liquid and glassy selenium have been carried out using density functional (400–773 K, 600 atoms) and classical force field (290–500 K, 5488 atoms) methods. Structural features (structure ...

    • Exceptional Microscale Plasticity in Amorphous Aluminum Oxide at Room Temperature 

      Frankberg, Erkka J.; Lambai, Aloshious; Zhang, Jiahui; Kalikka, Janne; Khakalo, Sergei; Paladino, Boris; Cabrioli, Mattia; Mathews, Nidhin G.; Salminen, Turkka; Hokka, Mikko; Akola, Jaakko Eemeli; Kuronen, Antti; Levänen, Erkki; Di Fonzo, Fabio; Mohanty, Gaurav (Peer reviewed; Journal article, 2023)
      Oxide glasses are an elementary group of materials in modern society, but brittleness limits their wider usability at room temperature. As an exception to the rule, amorphous aluminum oxide (a-Al2O3) is a rare diatomic ...

    • Highly ductile amorphous oxide at room temperature and high strain rate 

      Frankberg, Erkka J.; Kalikka, Janne; García Ferré, Francisco; Joly- Pottuz, Lucile; Salminen, Turkka; Hintikka, Jouko; Hokka, Mikko; Koneti, Siddardha; Douillard, Thierry; Le Saint, Bérangère; Kreiml, Patrice; Cordill, Megan J.; Epicier, Thierry; Stauffer, Douglas; Vanazzi, Matteo; Roiban, Lucian; Akola, Jaakko; Di Fonzo, Fabio; Levänen, Erkki (Journal article; Peer reviewed, 2019)
      Oxide glasses are an integral part of the modern world, but their usefulness can be limited by their characteristic brittleness at room temperature. We show that amorphous aluminum oxide can permanently deform without ...
