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…
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…
Towards Atomic-Scale Control over Structural Modulations in Quasi-1D Chalcogenides for Colossal Optical Anisotropy
Guodong Ren, Shantanu Singh, Gwan Yeong Jung +10
Optically anisotropic materials are sought after for tailoring the polarization of light. Recently, colossal optical anisotropy was reported in a quasi-one-dimensional chalcogenide…
Strong tunability of epitaxial relationship and reconstruction at improper ferroelectric interface
Xin Li, Yu Yun, Guodong Ren +4
The atomic structures at epitaxial film-substrate interfaces determine scalability of thin films and can result in new phenomena. However, it is challenging to control the interfac…
Antiferroelectricity with metastable polar state from Kittel model
Amit Kumar Shah, Xin Li, Guodong Ren +3
We have revisited the Kittel model that describes antiferroelectricity (AFE) in terms of two sublattices of spontaneous polarization with antiparallel couplings. By constructing th…
Giant coercivity and enhanced intrinsic anomalous Hall effect at vanishing magnetization in a compensated kagome ferrimagnet
Jonathan M. DeStefano, Elliott Rosenberg, Guodong Ren +9
Ferrimagnets that can be driven to magnetic compensation show promise for use in spintronics as they exhibit a finite anomalous Hall effect at zero magnetic field without having a…
