DOI: 10.1002/adma.202300257
Abstract: Antiferroelectrics, which undergo a field-induced phase transition to ferroelectric order that manifests as double-hysteresis polarization switching, exhibit great potential for dielectric, electromechanical, and electrothermal applications. Compared to their ferroelectric cousins, however, considerably fewer efforts have… read more here.

DOI: 10.1186/s11671-022-03655-x
Abstract: We demonstrate a non-volatile field-effect transistor (NVFET) with a 3-nm amorphous HfO 2 dielectric that can simulate the synaptic functions under the difference and repetition of gate voltage ( V G ) pulses. Under 100 ns… read more here.
