Strong substrate influence on atomic structure and properties of epitaxial VO2 thin films
Atul Atul, Majid Ahmadi, Panagiotis Koutsogiannis +2
The metal-insulator transition (MIT) observed in vanadium dioxide (VO2) has been a topic of great research interest for past decades, with the underlying physics yet not fully unde…
Giant electromechanical response from defective non-ferroelectric epitaxial BaTiO3 integrated on Si 100
Sandeep Vura, Shubham Kumar Parate, Subhajit Pal +15
Lead free, silicon compatible materials showing large electromechanical responses comparable to, or better than conventional relaxor ferroelectrics, are desirable for various nanoe…
Van der Waals Epitaxy of Pulsed Laser Deposited Antimony Thin Films on Lattice-matched and Amorphous Substrates
Daniel T. Yimam, Majid Ahmadi, Bart J. Kooi
Monatomic antimony thin films have recently attracted attention for applications in phase change memory, nanophotonics, and 2D materials. Although some promising results have been…
Real-time imaging of atomic potentials in 2D materials with 30 keV electrons
Sytze de Graaf, Majid Ahmadi, Ivan Lazić +2
Scanning transmission electron microscopy (STEM) is the most widespread adopted tool for atomic scale characterization of two-dimensional (2D) materials. Many 2D materials remain s…
Operando observation of reversible oxygen migration and phase transitions in ferroelectric devices
Pavan Nukala, Majid Ahmadi, Yingfen Wei +5
Unconventional ferroelectricity, robust at reduced nanoscale sizes, exhibited by hafnia-based thin-films presents tremendous opportunities in nanoelectronics. However, the exact na…
