▲ Abstract：

Spin-orbit–coupled Bose-Einstein condensates are a flexible experimental platform to engineer synthetic quantum many-body systems. In particular, they host the so-called stripe phase, an instance of a supersolid state of matter. The peculiar excitation spectrum of the stripe phase, a definite footprint of its supersolidity, has been difficult to measure experimentally. In this work, we performed in situ imaging of the stripes and directly observed both superfluid and crystal excitations. We investigated superfluid hydrodynamics and revealed a stripe compression mode, thus demonstrating that the system possesses a compressible crystalline structure. Through the frequency softening of this mode, we located the supersolid transition point. Our results establish spin-orbit–coupled supersolids as ideal systems to investigate supersolidity and its rich dynamics.

▲ Abstract：

Ferroelectrics have great potential for nonvolatile memory and next-generation electronics, but conventional ferroelectric oxide films generally suffer structural nonuniformity, interfacial depolarization, and performance degradation, particularly when downscaled to advanced technology nodes. We demonstrate uniform, wafer-scale synthesis and back-end-of-line–compatible integration of ultrathin van der Waals (vdW) high-dielectric constant ferroelectric oxide Bi₂SeO₅, retaining an optimal coercive field and robust ferroelectricity at monolayer thickness. Ultrathin vdW ferroelectric oxides formed atomically uniform interfaces with two-dimensional semiconductors and yielded ferroelectric field-effect transistor (FeFET) arrays with a low operating voltage (0.8 volts), exceptional cycling endurance (>1.5 × 10¹²cycles), fast write speed (20 nanoseconds), high on/off ratio (10⁶), 10-year retention, ultralow energy consumption (2.8 femtojoules per bit per square micrometer), and <5% device-to-device variation. Reconfigurable logic-in-memory circuits with these FeFETs function at supply voltages of <1 volt.

▲ Abstract：

Kinetics determine the growth behavior of thin films, particularly for atomically thin transition-metal dichalcogenides. Metal-organic (MO) chemical vapor deposition (CVD) offers promise for scalable growth, but the reactions are kinetically limited, leading to nanometer-scale domain size and carbon contaminations. Here, we unveil the fundamental kinetic limitations and overcome them by introducing oxygen-assisted MOCVD (oxy-MOCVD) technology. By tuning reactions with oxygen, MO precursors are converted into high-purity transition-metal oxides and chalcogens, producing aligned molybdenum disulfide (MoS₂) domains with a size and growth rate that are orders of magnitude larger than conventional MOCVD. The MoS₂is free of carbon impurities and exhibits average mobility exceeding 100 square centimeters per volt per second. The scalability of oxy-MOCVD is demonstrated by 150-millimeter single-crystal MoS₂wafers, proving the feasibility of industrial-scale production.

▲ Abstract：

Understanding the key mechanisms that control the tectonic deformation of the continents remains a fundamental challenge in geodynamics. We present a high-resolution geodetic velocity field of the Tibetan Plateau, which shows that a few major strike-slip fault systems separate regions of more uniformly distributed deformation. We suggest that focused strain on major fault systems is enabled by relatively low-viscosity ductile shear zones extending through the lithosphere beneath the seismically active fault planes. Simple model calculations show that high slip rates on the Kunlun Fault enable east-west extension to be distributed broadly across the relatively weak southern and central Tibetan Plateau. Activation of the Kunlun fault in the Miocene at the same time as the onset of rifting in the north-south grabens suggests a causal relationship.
