Optoelectronic synapses are currently drawing significant attention as fundamental building blocks of neuromorphic computing to mimic brain functions. In this study, a two‐terminal synaptic device based on a doped PdSe2 flake is proposed to imitate the key neural functions in an optical pathway. Due to the wavelength‐dependent desorption of oxygen clusters near the intrinsic selenide vacancy defects,...
PbYb0.5Nb0.5O3 (PYN)‐based ceramics, featured by their ultra‐high phase‐switching field and low sintering temperature (950 °C), are of great potential in exploiting dielectric ceramics with high energy storage density and low preparation cost. However, due to insufficient breakdown strength (BDS), their complete polarization‐electric field (P‐E) loops are difficult to be obtained. Here, to fully reveal...
Owing to the current global scenario of environmental pollution and the energy crisis, the development of new dielectrics using lead‐free ceramics for application in advanced electronic and energy storage systems is essential because of the high power density and excellent stability of such ceramics. Unfortunately, most of them have low breakdown strength and/or low maximum polarization, resulting...
Dielectric ceramic capacitors have attracted increasing attention as advanced pulsed power devices and modern electronic systems owing to their fast charge/discharge speed and high power density. However, it is challenging to meet the urgent needs of lead‐free ceramics with superior energy storage performance in practical applications. Herein, a strategy for the composition and structural modification...
Polarization field engineering of piezoelectric materials is considered as an advisable strategy in fine‐tuning photocatalytic performance which has drawn much attention recently. However, the efficient charge separation that determines the photocatalytic reactivities of these materials is quite restricted. Herein, a judicious combination of piezoelectric and photocatalytic performances of BiOX/BaTiO...
Graphene has attracted great interests in various areas including optoelectronics, spintronics, and nanomechanics due to its unique electronic structure, a linear dispersion with a zero bandgap around the Dirac point. Shifts of Dirac cones in graphene creates pseudo‐magnetic field, which generates an energy gap and brings a zero‐magnetic‐field analogue of the quantum Hall effect. Recent studies have...
The synthesis of a chiral fluorescent silole derivative containing l‐leucine methyl ester moiety (Silole–Leu) is reported by B. S. Li, B. Z. Tang, co‐workers on page 6593. Silole–Leu exhibits aggregation‐induced emission and circular dichroism, and circular polarized luminescence. Silole–Leu is endowed with the ability to self‐assemble into nano/micro helical luminescent fibers and their dimensions...
By introducing chiral leucine pendants to silole scaffold, leucine‐containing silole (Silole‐Leu) is synthesized and it is endowed with not only aggregation‐induced emission and circular dichroism, but excellent chiral polarized luminescence as well. Silole–Leu also has the capacity to self‐assemble into nano/micro helical luminescent fibers and the dimension of the fibers can be tuned by adjusting...
