Defect-engineered scaling of lead-free ferroelectrics with ultralow-voltage switching
Reza Ghanbari, Jiayue Wang, Harikrishnan KP +9
Scaling ferroelectrics to nanometer thicknesses remains a central challenge for low-power, nonvolatile electronics, as leakage currents increasingly dominate with reduced dimension…
Mind the Gap -- Imaging Buried Interfaces in Twisted Oxide Moirés
Harikrishnan KP, Xin Wei, Chia-Hao Lee +10
The ability to tune electronic structure in twisted stacks of two-dimensional (2D) materials has motivated the exploration of similar moiré physics with twisted oxide membranes. Du…
Improper Ferroelectricity at the Monolayer Limit
Yilin Evan Li, Harikrishnan KP, Haidong Lu +20
Ultrathin ferroelectric films with out-of-plane polarization and high Curie temperatures are key to miniaturizing electronic devices. Most ferroelectrics employed in devices are pr…
Electron ptychography reveals a ferroelectricity dominated by anion displacements
Harikrishnan KP, Ruijuan Xu, Kinnary Patel +9
Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here…
