Oxygen passivation mediated tunability of trion and excitons in MoS
Pranjal Kumar Gogoi, Zhenliang Hu, Qixing Wang +10
Using wide spectral range in situ spectroscopic ellipsometry with systematic ultra high vacuum annealing and in situ exposure to oxygen, we report the complex dielectric function o…
Sub-Nanometer Channels Embedded in Two-Dimensional Materials
Yimo Han, Ming-Yang Li, Gang-Seob Jung +5
Two-dimensional (2D) materials are among the most promising candidates for next-generation electronics due to their atomic thinness, allowing for flexible transparent electronics a…
Nitrogen-doped Nanoporous Carbon Membranes Functionalized with Co/CoP Janus-type nanocrystals as Hydrogen Evolution Electrode in Both Acid and Alkaline Environment
Hong Wang, Shixiong Min, Qiang Wang +9
Self-supported electrocatalysts being generated and employed directly as electrode for energy conversion has been intensively pursued in the fields of materials chemistry and energ…
Disorder Dependent Valley Properties in Monolayer WSe2
Kha Tran, Akshay Singh, Joe Seifert +7
We investigate the effect on disorder potential on exciton valley polarization and valley coherence in monolayer WSe2. By analyzing polarization properties of photoluminescence, th…
Synthesis of Single-crystal-like Nanoporous Carbon Membranes and Their Applications in Overall Water Splitting
Hong Wang, Shixiong Min, Chun Ma +17
Nanoporous graphitic carbon membranes with defined chemical composition and pore architecture are novel nanomaterials that are actively pursued. Compared to easy-to-make porous car…
