Ferroelectric Field‐Effect‐Transistor Integrated with Ferroelectrics Heterostructure

Advanced Science, 2022
AbstractTo address the demands of emerging data‐centric computing applications, ferroelectric field‐effect transistors (Fe‐FETs) are considered the forefront of semiconductor electronics owing to their energy and area efficiency and merged logic–memory functionalities. Herein, the fabrication and application of an Fe‐FET, which is integrated with a van

Switchable tribology of ferroelectrics

Nature Communications
AbstractSwitchable tribological properties of ferroelectrics offer an alternative route to visualize and control ferroelectric domains. Here, we observe the switchable friction and wear behavior of ferroelectrics using a nanoscale scanning probe—down domains have lower friction coefficients and show slower wear rates than up domains and can be used as ...

Sliding induced multiple polarization states in two-dimensional ferroelectrics [PDF]

Nature Communications, 2022
When the atomic layers in a non-centrosymmetric van der Waals structure slide against each other, the interfacial charge transfer results in a reversal of the structure’s spontaneous polarization.
