Researchers engineered lead-free BCZT/STO superlattice capacitors that achieved a recoverable energy storage density of 12.6 J/cm³ with near-99 % efficiency at 920 kV/cm, while maintaining stable performance through 2 × 108 charge–discharge cycles. Atomic-scale measurements indicate that the superlattice changes the size and spatial organization of polar nanoregions, while a strain-gradient-related internal field also contributes to the observed energy-storage behavior.
A research team led by Professor Ji-Sang Park of the Sungkyunkwan University, SKKU Advanced Institute of Nanotechnology (SAINT), in collaboration with Professor Yong-Young Noh's team at Pohang University of Science and Technology (POSTECH) and the teams of Professors Ao Liu and Huihui Zhu at the University of Electronic Science and Technology of China (UESTC), has successfully overcome the critical oxidation problem of conventional eco-friendly, lead-free perovskite semiconductors and developed a p-type transistor with world-class performance.
A new project led by the Department of Energy's SLAC National Accelerator Laboratory brings together scientists and engineers from national labs, universities and industry to build a platform that transforms today's complex research environment into self-driving laboratories controlled by Super Intelligence (SI) systems that can evaluate and respond autonomously to rapidly changing needs.
Traditional photodetectors rely on fixed designs: responsivity, dynamic range and spectral selectivity are set during fabrication. Silicon, the dominant material, has a relatively fixed bandgap and limited carrier mobility, making broadband, high-speed and multifunctional detection difficult.
