A key aspect of how the brain learns and enables decision-making processes is through synaptic interactions. Electrical transmission communication in a network synapses are modulated by extracellular fields generated ionic chemical gradients. Emulating such spatial interactions synthetic networks can be potential use for neuromorphic learning hardware implementation artificial intelligence. Here, we demonstrate that hydrogen-doped perovskite nickelate devices, electric bias across single...
Abstract Materials with field-tunable polarization are of broad interest to condensed matter sciences and solid-state device technologies. Here, using hydrogen (H) donor doping, we modify the room temperature metallic phase a perovskite nickelate NdNiO 3 into an insulating both metastable dipolar space-charge polarization. We then demonstrate transient negative differential capacitance in thin film capacitors. The caused by long-range movement trapping protons dominates when electric field...
Design of hardware based on biological principles neuronal computation and plasticity in the brain is a leading approach to realizing energy- sample-efficient AI learning machines. An important factor selection building blocks identification candidate materials with physical properties suitable emulate large dynamic ranges varied timescales signaling.

An external electric field can affect the growth dynamics of croconic acid (CA) films, especially heterogeneous nucleation process, as evidenced by shift temperature dependence rate in field.
VO2 thin films were grown on conducting oxide underlayer SrRuO3 buffered SrTiO3 (111) and Si/SiO2 substrates, respectively, using sputtering. X-ray diffraction phi-scans revealed the epitaxial nature of polycrystalline structure for Si/SiO2. photoelectron spectroscopy confirms a dominant presence V4+ in both establishes high-quality growth single-phase films. Temperature electric-field driven metal-insulator-transition in-plane out-of-plane configurations investigated. Depending...
Device applications often require thin film growth with quasi-two-dimensional morphology and crystallization, which are not always compatible. In this work, we exploit the method of low-temperature deposition followed by restrained crystallization (LDRC) in crystalline organic molecular films, tend to grow three-dimensionally random orientations. We demonstrate that for 2-methylbenzimidazole, a ferroelectric tends crystallize spherulites, films can be grown using LDRC highly oriented polar...
Abstract This paper describes the 3D printing of a ternary composite polydimethylsiloxane (PDMS) and nanoparticles iron oxide barium titanate. The was printed using commercially available printer. Thermal curing during allowed for overall low process times few minutes. Scanning electron microscopy indicated uniform layers. resulting films showed ferromagnetic behaviour, applicability in magnetic actuation piezoelectric energy harvesting.
Oxygen-ion conductors have traditionally been studied in the context of high temperature (≈ 873 to 1773 K) energy conversion and sensor technologies.

The rf radiation spectrum is central to wireless and radar systems among numerous high-frequency device technologies. Here, we demonstrate sensing of signals in the technologically relevant 2.4-GHz range utilizing vanadium dioxide (${\mathrm{VO}}_{2}$), a quantum material that has garnered significant interest for its insulator-to-metal transition. We find electrical resistance both stoichiometric as well off-stoichiometric oxide films can be modulated with wave exposures from distance....
