The AC poling cycle dependence of Mn-doped Pb(Mg1/3Nb2/3)O3-0.3Pb(Zr.Ti)O3 (PMN-0.3PZT) single crystals (SC) produced via the solid-state crystal growth (SSCG) method was investigated. The piezoelectric strain and charge constants, d 33 ＝ 1130 pC/N, g 33 = 42.7 × 10−3 Vm/N, and mechanical quality factor Q m = 800 were obtained under conditions of 1...

Spatial light modulations (SLM) utilizing the magneto-optical (MO) effect of magnetic materials are expected to offer fast switching and small pixel sizes as small as the wavelength of the light. However, the small MO effect is a major issue. In this paper, we report a thermomagnetic recording of highly bismuth-substituted garnet film, known for la...

Reservoir computing and predictive coding together yield a computational model for exploring how neuronal dynamics in the mammalian cortex underpin temporal signal processing. Here, we construct an in-silico model of biological neuronal networks grown on microelectrode arrays and explore their computing capabilities through a sine wave prediction t...

Sodium potassium niobate (KNN) and KNN-based ceramics are considered viable alternatives to lead-based piezoelectric ceramics. Their chemical composition is the key to their phase transitional behaviour, which determines their functional properties. On the other hand, the microstructure is another factor that crucially contributes to shaping the pr...

A novel plasmonic sensor, which is composed of a metal-insulator-metal (MIM) waveguide and a coupled split-square-ring resonator, is proposed and investigated by utilizing the two-dimensional (2D) finite-difference time-domain (FDTD) method. The optimized results demonstrate that the proposed sensor is highly sensitive to variations of refractive i...

Changes in the diffusion coefficient of supported lipid bilayers affected by their interaction with the substrate were evaluated by fluorescence recovery after photobleaching under different surface charges and ambient conditions (presence of divalent ions in solution). The diffusion coefficients of each leaflet were estimated separately by quenchi...

NaNbO3, AgNbO3, and KNbO3 with ABO3-type perovskite systems are known to possess good ferroelectric properties. In their traditional average structure, a change in the A-site ion size changes the involved tolerance factor. Herein, we directly determined the rattling space of each atom through local structure analysis. By combining a pair distributi...

A dual-layer photonic spiking neural network (PSNN) was constructed, where multiple optically pumped spin vertical-cavity surface-emitting lasers (Spin-VCSELs) were proposed as spiking neurons. Based on a detailed theoretical analysis of leaky integrate-and-fire (LIF) and refractory period characteristics of Spin-VCSEL neurons, the training and tes...

This study explores the potential of Ge-enhanced Cu2SnS3 (CTS) thin-films as photoelectrode materials for water splitting grown through a simple sulfurization process. The addition of Ge to CTS enabled tuning the bandgap and improved the photocurrent density. Films sulfurized at 520 °C exhibit enhanced grain size and reduced grain boundaries, which...
