Journal ArticleDOI
Large-grain MBE-grown GaSe on GaAs with a Mexican hat-like valence band dispersion
Mingwei Chen,HoKwon Kim,Dmitry Ovchinnikov,Agnieszka Kuc,Thomas Heine,Olivier Renault,Andras Kis +6 more
TL;DR: In this paper, the full valence band structure of nominal bilayer GaSe is revealed by photo-emission electron momentum microscopy (k-PEEM), confirming the presence of a distorted valence bands near the Γ point.
Journal ArticleDOI
Ultrahigh capacitance of nanoporous metal enhanced conductive polymer pseudocapacitors
Ying Hou,Luyang Chen,Ling Zhang,Jianli Kang,Takeshi Fujita,Jianhua Jiang,Mingwei Chen,Mingwei Chen +7 more
TL;DR: In this article, a dealloyed nanoporous metal/conductive polymer hybrid electrode was used for supercapacitors with an energy density of ∼100 Wh kg −1 in a three-electrode, comparable to NiMH batteries.
Journal ArticleDOI
Extraordinary Supercapacitor Performance of a Multicomponent and Mixed‐Valence Oxyhydroxide
TL;DR: A novel multicomponent mixed-valence oxyhydroxide-based electrode synthesized by electrochemical polarization of a de-alloyed nanoporous NiCuMn alloy possesses an extraordinarily wide working-potential window of 1.8 V in an aqueous electrolyte, which far exceeds the theoretically stable window of water.
Journal ArticleDOI
Raman characterization of pseudocapacitive behavior of polypyrrole on nanoporous gold
TL;DR: This study provided direct evidence that the stability degradation of PPy is caused by the irreversible transition between oxidation and reduction states of P py, which is associated with the permanent deformation of P Py molecular chains subjected to applied potentials.
Journal ArticleDOI
Nanocrystalline grain structures developed in commercial purity Cu by low-temperature cold rolling
TL;DR: In this article, the formation of nanocrystalline grain structures is attributed to dynamic grain refinement mechanisms activated by the low-temperature continuous plastic deformation that leads to ultrahigh densities of dislocations.
