Increased heavy ion single-event upset (SEU) sensitivity of radiation-harden 65-nm dual interlocked cell (DICE) static random access memory (SRAM) is observed after total ionizing dose (TID) irradiation. The mechanism the increased SEU cross section analyzed by stability testing and TCAD simulation. Cell result shows that noise margin diminished TID-induced threshold voltage shifts. Critical charge inducing reduced in TID-irradiated cell, because it more susceptible to noise. Moreover,...
High-temperature ceramic/polymer nanocomposites with large energy density as the reinforcement exhibit great potential for storage applications in modern electronic and electrical power systems. Yet, a general drawback is that increased dielectric constant usually achieved at cost of decreased breakdown strength, thus leading to moderate improvement even displaying marked deterioration under high temperatures electric fields. Herein, new strategy reported simultaneously improve strength...
Abstract The self‐assembling molecule 2PACz tends to aggregate in thin films, which negatively impacts the performance of organic solar cells (OSCs) when used as a hole‐transporting layer (HTL), particularly large‐area devices. To overcome this, binary conjugated molecular system incorporating carbazole (Cz), shares similar backbone with 2PACz, is introduced. Despite strong aggregation tendencies and Cz individually, their blend forms homogeneous films due hydrogen bonding interactions...
