Barrier‐Assisted Plasma Doping for Spatially Selective Resistance Engineering in MoS2 Transistors

Advanced Materials, EarlyView.
Barrier‐assisted NH3 plasma doping enables damage‐free, spatially selective carrier modulation in monolayer MoS2 transistors. An ultrathin pV3D3/Al2O3 protective‐dielectric stack acts as a chemical filter that allows NHx radicals to reach the MoS2 surface while blocking plasma damage. This process achieves a high electron concentration of 4.3 × 1013 cm−

Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater

Advanced Materials, EarlyView.
Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Quantitative desorption analysis of ultra large scale integration materials by thermal desorption spectroscopy.

BUNSEKI KAGAKU, 1994
四重極質量分析計を用いた昇温脱離ガス分析法により半導体集積回路材料からの脱離無機ガスの定量分析法について検討した.既知量の水素をイオン注入したSiウェハーを用いて,昇温脱離スペクトルのピーク面積から測定再現性,定量性について評価した.繰り返し測定の再現性は,水素分子の脱離量(5×1014H2/cm2)に対し相対標準偏差で5%内に入ることを確認した.その脱離量はイオン注入ドーズ量に比例し信頼性の高い検量線が作成でき,フッ化水素酸水溶液で処理したSi(001)表面のダングリングボンドはほとんどすべて水素終端されていることを水素分子の脱離量から検証した.又,水素に対する検量線と四重極質量分析計のフラグメンテーションファクターやイオン化難易度を考慮することにより ...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.
