Dielectric and Gate Metal Engineering for Threshold Voltage Modulation in Enhancement Mode Monolayer MoS2 Field Effect Transistors

Advanced Materials, EarlyView.
Enhancement‐mode monolayer MoS2 FETs with low threshold voltage are essential for low‐power electronics. The threshold voltage can be tuned by the gate metal work function when the semiconductor/dielectric interface is clean. Interfaces between monolayer MoS2 and ZrO2 or hBN allow effective work‐function modulation of the threshold voltage, in contrast

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Undercoordinated Molybdenum Catalysts Enable Ultrafast Quasi‐Solid Sulfur Chemistry in Sodium‐Sulfur Batteries

Advanced Materials, EarlyView.
An unsaturated coordination chemistry strategy activates a quasi‐solid‐state redox pathway by strengthening NaPSs adsorption and accelerating redox conversion kinetics, thereby overcoming the kinetic bottlenecks that limit high‐rate performance. In situ transmission electron microscopy, combined with newly developed Na‐ion diffusion descriptors ...

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

Advanced Materials, EarlyView.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet

Low Resistance Interphase Formation at the PEO‐LiTFSI|LGPS Interface in Lithium Solid‐State Batteries

Advanced Materials Interfaces, EarlyView.
Interfacial charge transfer and low‐resistance interphase formation between PEO‐based polymer and Li10GeP2S12 solid electrolytes are investigated using multi‐electrode impedance spectroscopy and advanced analytical techniques such as XPS and ToF‐SIMS.

Polarography of sulfur compounds

1987
Publisher Summary This chapter discusses the polarography of sulfur compounds. Many sulfur compounds, both inorganic and organic, exhibit electrochemical behavior that is useful for analytical purposes. Simple polarography with a dropping mercury electrode can provide a versatile method for the simultaneous identification and quantitative ...

Low Sulfur Compounding

Rubber Chemistry and Technology, 1934
Abstract Since the beginning of the rubber industry, sulfur dosages used for soft rubber have declined from 20 to 2 or 3 per cent customary today. The decline is still under way, and present sulfur ratios are high in comparison with what is actually required to produce satisfactory commercial vulcanization—fractions of 1 per cent. Vulcanization

Sulfur-containing Compounds

1978
The weak sulfur-sulfur bond in elemental sulfur allows carbon-centred radicals and thiyl radicals to effect Sh2 reactions at such sulfur atoms leading to the formation of poly sulfides. For example [1], $$ Me_2 \dot CCN + S_8 \to Me_2 (CN)CS_n C(CN)Me_2 $$ and [2] $$ MeSSMe\xrightarrow{{120^\circ C}}2MeS \cdot $$ $$ MeS \cdot + S_8 ...

Organometallic Sulfur Compounds

1984
Abstract The organometallic chemistry of S 2- and SH - ligands is outlined. The ability of substituent free sulfur to act as a two, four, or six electron donor and of the SH unit to act as a one, three, or five electron donor is the reason for structural diversity and the preference for polynuclear complexes.
