Tripling of the Superconducting Critical Current Density in BaFe(AsP) Retained After Pressure Release
Jiangteng Liu, Alex Lopez, Daniel Slone +5
Superconducting performance is tunable not only via chemical modification or defect engineering, but also through external parameters such as pressure, though this method remains l…
Atomic-Scale Observation of Symmetry Breaking in Altermagnetic MnTe
Guodong Ren, Jonathan M. DeStefano, Xiao-Wei Zhang +20
The recent discovery of altermagnetism has sparked growing interest in compensated magnetic systems as promising platforms for highly scalable spintronics. Altermagnetism is a dist…
Twist-induced Out-of-plane Ferroelectricity in Bilayer Hafnia
Jian Huang, Gwan Yeong Jung, Pravan Omprakash +6
Ferroelectric HfO2 is a promising candidate for next-generation memory devices due to its CMOS compatibility and ability to retain polarization at nanometer scales. However, the po…
Hole-doping reduces the coercive field in ferroelectric hafnia
Pravan Omprakash, Gwan Yeong Jung, Guodong Ren +1
Ferroelectric hafnia (HfO2) holds promise for next-generation memory and logic applications because of its CMOS compatibility. However, the high coercive field required for polariz…
Sub-nm2 ferroelectric domains via charged 180 degree walls in ZrO2
Nashrah Afroze, Hamoon Fahrvandi, Guodong Ren +31
Flat phonon bands in fluorite ferroelectrics (HfO2 or ZrO2) shrink polar domains laterally to an irreducible half-unit-cell width (0.27 nm) within which the vertical arrangement of…
Unveiling the Shortwave Absorption Spectra of Alumina Aerosols: Implications for Solar Radiation Modification
Taveen Singh Kapoor, Prabhav Upadhyay, Jian Huang +12
Alumina is proposed for Stratospheric Aerosol Injection (SAI)-based solar radiation modification due to its presumed ability to scatter sunlight strongly while absorbing weakly. Al…
