Polymer film capacitors have been widely used in electronics and electrical power systems due to their advantages of high densities, fast charge-discharge speed, great stability. However, the exponential increase conduction with temperature applied electric field substantially degrades capacitive performance dielectric polymers at elevated temperatures. Here, first example controlling energy level charge traps all-organic crosslinked by tailoring molecular structures that significantly...
Abstract Ferrimagnetic insulator materials are the enabling technology for development of next‐generation magnetic devices with low power consumption, high operation speed, and miniaturization capability. To achieve a high‐density memory device, combined realization robust saturation magnetization ( M s ), controllable anisotropy, resistivity (ρ) highly demanded. Despite significant efforts that have been made recently, simultaneously achieving enhancements in these properties soft material...
Effective pyroelectric coefficients as large 5 μC/cm2 °C, with peak responsivities at approximately 50 were obtained from compositionally graded barium strontium titanate ferroelectric thin film devices formed on silicon using unbalanced magnetron sputter deposition. These effective are nearly two orders of magnitude larger than those observed conventional detectors.
Organic solar cells (OSCs) with high performance were prepared using poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and [2-(3,6-dibromo-9H-carbazol-9-yl)ethyl]phosphonic acid (Br-2PACz) double-layer films as the anode interface. By spin-coating a layer of Br-2PACz on PEDOT:PSS to form PEDOT:PSS/Br-2PACz dual-anode interface, both Jsc FF device can be increased simultaneously, resulting in 27.84 mA cm-2 78.18%. The promising result indicates that interface is an effective...
In this work, the (1-x)CaWO4-xNa2WO4 (x = 0.1, 0.2, denoted as 0.9CW-0.1NW and 0.8CW-0.2NW, respectively) ultralow-loss microwave dielectric ceramics were prepared via solid-state reaction method. Using low melting-point Na2WO4 sintering aid to prepare CaWO4Na2WO4 composite ceramics, temperature of CaWO4 was successfully reduced while maintaining excellent performance. The optimal properties have been achieved at 900 °C for ceramic: εr 9.0, Q × f 105660 GHz, tanδ 1.1 10−4 τf −35.4 ppm/°C a...
Although many dielectric polymers exhibit high energy storage density (Ue) with enhanced dipolar polarization at room temperature, the substantially increased electric conduction loss applied fields and temperatures remains a great challenge.
