Room-temperature polar skyrmions, which have been recently discovered in oxide superlattice, received considerable attention for their potential applications nanoelectronics owing to nanometer size, emergent chirality, and negative capacitance. For practical applications, manipulation using external stimuli is a prerequisite. Herein, we study the dynamics of individual skyrmions at nanoscale via situ scanning transmission electron microscopy. By monitoring electric-field-driven creation,...

Hafnium oxide-based ferroelectric materials have been researched extensively for high-speed, low-power nonvolatile memory devices. However, doping HfO2 through atomic layer deposition (ALD) cycles primarily aims to enhance specific properties but also introduces challenges in balancing performance and reliability. Therefore, understanding the of intrinsic crystalline HfO2-based developing undoped devices with exceptional comprehensive are crucial. Here, we successfully fabricated...

Pulmonary arterial hypertension (PAH) is a chronic disorder characterized by the excessive proliferation of pulmonary smooth muscle cells (PASMCs). Recent studies indicate that Mitochondrial fusion protein 2 (Mfn2) maintains intracellular calcium (Ca2+) homeostasis via mitochondria-associated endoplasmic reticulum membranes (MAMs) pathway, thereby inhibiting PASMCs and reducing artery pressure. However, precise mechanisms remain unclear. This study explored roles Mfn2 IP3R3 in PAH...

Ferroelectric Rashba semiconductors (FERSCs) have recently attracted intensive attention due to their giant bulk parameter, αR, which results in a locking between the spin degrees of freedom and switchable electric polarization. However, integration FERSCs into microelectronic devices has provoked questions concerning whether effect can persist when material thickness is reduced several nanometers. Here we find that αR keep large value 2.12 eV Å 5.0 nm thick GeTe film. The behavior with be...
