Symposium Advances in Powder and Ceramic Materials Science
Presentation Title Tunable Self-assembled Metal and Metal-oxide Nanostructures Embedded in Complex Concentrated Oxide Thin Films
Author(s) William Bowman, Xin Wang, Huiming Guo
On-Site Speaker (Planned) William Bowman
Abstract Scope Complex concentrated oxides (CCOs), such as the rock salt (Co,Cu,Mg,Ni,Zn)O, show entropy-enhanced stability and compositionally tunable properties desired for next-generation functional materials like cathodes, solid electrolytes, catalysts, and thermal insulators. However, metal and metal-oxide nanostructure design as an affordable and efficient route to tune properties is less investigated and more complicated in complex concentrated materials. Here, we use pulsed laser deposition (PLD) to fabricate rock salt and perovskite oxide CCO thin films with 1D, 2D, and 3D nanostructures. We tunable formation of metal- and metal oxide-CCO nanocomposite structures during PLD thin film growth. The mechanisms of nanostructure formation are under detailed investigation down to the atomic scale using a suite of physical and chemical characterization methods coupled with computational calculations of point defect complex formation energetics. The thin films’ functional and electrochemical properties are also under investigation and will be discussed.
