High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, Volume 8, Issue 5, May 2026.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Mobility enhancement and highly efficient gating of monolayer MoS2 transistors with Polymer Electrolyte

, 2012
We report electrical characterization of monolayer molybdenum disulfide (MoS2) devices using a thin layer of polymer electrolyte consisting of poly(ethylene oxide) (PEO) and lithium perchlorate (LiClO4) as both a contact-barrier reducer and channel ...

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

Small, EarlyView.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Safe Separation of the Low-Concentration and Oxygen-Bearing Coal Mine Methane by Vacuum Pressure Swing Adsorption

Adsorption Science & Technology, 2014
Pressure swing adsorption (PSA) is a suitable method to enrich the concentration of methane in coal mine methane (CMM) separation processes. However, traditional PSA processes for low-concentration CMM can easily increase the concentration of methane to ...

Hydrogen and Oxygen Defect Engineering in Amorphous‐IGZO Thin‐Film Transistors by Rapid Thermal Annealing Ambient

physica status solidi (a), Volume 223, Issue 8, 22 April 2026.
This study investigates how rapid thermal annealing atmospheres control defect dynamics in amorphous IGZO thin‐film transistors with HfO2 dielectrics deposited by thermal atomic layer deposition. The interplay among hydrogen interstitials, oxygen interstitials, and oxygen vacancies are shown to govern device stability under positive/negative bias ...
