Noise‐Blocking Interfacial Lamination of Small‐Molecule Acceptors for Enhanced Signal Clarity in Organic Photodetectors

Carbon Energy, EarlyView.
The structural design strategy employing the Y6‐BO interfacial lamination suppresses dark current by limiting solvent‐induced interfacial damage through the formation of uniformly arranged interfaces while optimizing charge transport to achieve superior detectivity.

Experimental and numerical studies of a new thermionic emitter structure based on oxide coated carbon nanotubes operating at large emission currents

, 2007
We have developed a thermionic cathode capable of high emission currents. The structure of this cathode is oxide coated carbon nanotubes (CNTs) on a tungsten (W) substrate.

Reconfigurable Logic Operation of MoTe2 Homojunction Enabled by Staggered Double‐Sided Contacts

Electron, EarlyView.
A gap adjacent to an electrode in the MoTe2 SDC transistor enables polarity reconfiguration, switching between p‐type and n‐type depending on bias polarity. This reconfiguration is ensured when the absolute bias voltage is less than the gate voltage, yielding a near‐ideal subthreshold swing of 67.6 mV/dec and on/off ratios of 104–106.

Van der Waals ferroelectric semiconductor tunnel junction with ultra‐low switching voltage

InfoMat, EarlyView.
Ferroelectric tunnel junctions are promising building blocks for energy‐efficient memory and brain‐inspired computing, but their practical use is limited by the relatively high voltages required for operation. Here, we develop an all‐two‐dimensional ferroelectric tunnel junction based on AgBiP2Se6 that enables reliable memory operation below 0.2 V and ...

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,
