Structural modulation in potassium birnessite single crystals
Liliia D. Kulish, Pavan Nukala, Rick Scholtens +3
We report on the growth of single-crystal potassium birnessite (K0.31MnO2*0.41H2O) and present both the average and local structural characterization of this frustrated magnetic sy…
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…
Guidelines for the stabilization of a polar rhombohedral phase in epitaxial Hf0.5Zr0.5O2 thin films
Pavan Nukala, Yingfen Wei, Vincent de Haas +3
The unconventional Si-compatible ferroelectricity in hafnia-based systems, which becomes robust only at nanoscopic sizes, has attracted a lot of interest. While a metastable polar…
Structure and magnetic properties of epitaxial CaFe2O4 thin films
Silvia Damerio, Pavan Nukala, Jean Juraszek +3
CaFe2O4 is a highly anisotropic antiferromagnet reported to display two spin arrangements with up-up-down-down (phase A) and up-down-up-down (phase B) configurations. The relative…
Stabilization of phase-pure rhombohedral HfZrO4 in Pulsed Laser Deposited thin films
Laura Bégon-Lours, Martijn Mulder, Pavan Nukala +6
Controlling the crystalline structure of Hafnium Zirconate and its epitaxial relationship to a semiconducting electrode has a high technological interest, as ferroelectric material…
Direct epitaxial growth of polar (1-x)HfO2-(x)ZrO2 ultra-thin films on Silicon
Pavan Nukala, Jordi Antoja-Lleonart, Yingfen Wei +3
Ultra-thin Hf1-xZrxO2 films have attracted tremendous interest owing to their Si-compatible ferroelectricity arising from polar polymorphs. While these phases have been grown on Si…
