Domain-Wall Mediated Polarization Switching in Ferroelectric AlScN: Strain Relief and Field-Dependent Dynamics
Xiangyu Zheng, Charles Paillard, Dawei Wang +4
While scandium-doped aluminum nitride (AlScN) exhibits robust ferroelectricity and excellent thermal stability, its utility is limited by an exceptionally high coercive field ($E_c…
Effects of particle-hole fluctuations on the superfluid transition in two-dimensional atomic Fermi gases
Junru Wu, Zongpu Wang, Lin Sun +6
Proper treatment of the many-body interactions is of paramount importance in our understanding of strongly correlated systems. Here we investigate the effects of particle-hole fluc…
Magnetic exchange coupled nonreciprocal devices for cryogenic memory
Josep Ingla-Aynés, Lina Johnsen Kamra, Franklin Dai +5
As computing power demands continue to grow, superconducting electronics present an opportunity to reduce power consumption by increasing the energy efficiency of digital logic and…
Towards a deeper fundamental understanding of (Al,Sc)N ferroelectric nitrides
Peng Chen, Dawei Wang, Alejandro Mercado Tejerina +4
Density Functional Theory (DFT) calculations, within the virtual crystal alloy approximation, are performed, along with the development of a Landau-type model employing a symmetry-…
