Integer Error Control Codes for Non-ECC DRAM Memories", Horizons in Computer Science Research

A large percentage of dynamic random access memories (DRAMs) are not protected by error control codes (ECCs). Because of this, in these so-called non-ECC DRAMs, every erroneous bit may cause file corruptions and even system crashes. In order to avoid such an outcome, it is necessary to either modify the existing hardware or reduce the effective ...

Electrochemical Doping for Absorption and Conductivity Tuning of P(NDI2OD‐T2) Films

Advanced Electronic Materials, EarlyView.
Electrochemical doping of P(NDI2OD‐T2) films allows for tuning the degree of doping both in liquid electrolytes as well as in the solid state. The nature of the doped species is elucidated by UV–vis spectroscopy and accompanying DFT calculations. Correlations between maximum conductivities and the presence of mixed valence states, (specifically neutral/

Using Dopants as Agents to Probe Key Electronic Properties of Organic Semiconductors

Advanced Electronic Materials, EarlyView.
Dopants are typically used in organic electronics to enhance conductivity, but here their potential is demonstrated as probes for fundamental material properties. By integrating experimental data and multiscale simulations, it is shown how dopant ionization and conductivity measurements enable accurate extraction of ionization potential and Coulomb ...

Programmable Cryogenic Memory in a Ge/GeSi Heterostructure

Advanced Electronic Materials, EarlyView.
A highly programmable memory function that occurs due to a charge tunneling and trapping mechanism is demonstrated in a Ge/GeSi heterostructure field‐effect thransistor. Over three orders‐of‐magnitude control over the conductance state of the device is achieved using either the device SET or the device RESET process, suggesting potential for ...

Revealing Localized Dark‐Exciton Populations in 2D Perovskites via Magneto‐Optical Microscopy

Advanced Energy Materials, EarlyView.
Magneto‐optical microscopy is used on metal halide perovskites for the first time to reveal the heterogenous nature of exciton emission in 2D perovskites. The study reveals that the morphology of 2D perovskite thin films has a crucial impact on localisation of bright and dark excitons.

The effects of agricultural machinery services and land fragmentation on farmers' straw returning behavior

Agribusiness, EarlyView.
Abstract Straw returning is important for rural ecological management and sustainable agricultural development. Using farm survey data for Anhui Province, China, in 2020, we applied the double‐hurdle model to investigate the impact of agricultural machinery services and land fragmentation on farmers' straw‐returning behavior, and to explore the ...
