Dongxing Yang,Aruna Velamakanni,Gulay Bozoklu,Sungjin Park,Meryl D. Stoller,Richard D. Piner,Sasha Stankovich,Inhwa Jung,Daniel Field,Carl A. Ventrice,Rodney S. Ruoff +10 more
TL;DR: In this paper, several nanometer-thick graphene oxide films were exposed to nine different heat treatments (three in Argon, three in Argon and Hydrogen, and three in ultra-high vacuum), and also a film was held at 70°C while being exposed to a vapor from hydrazine monohydrate.
Journal ArticleDOI
Hydroxyl groups on oxide surfaces: NiO(100), NiO(111) and Cr2O3(111)
D. Cappus,C. Xu,D. Ehrlich,B. Dillmann,Carl A. Ventrice,K. Al Shamery,Helmut Kuhlenbeck,Hans-Joachim Freund +7 more
TL;DR: In this article, the presence of hydroxyl groups at the surfaces of NiO(100), NiO (111), and Cr2O3(111) has been studied using different surface sensitive spectroscopies.
Journal ArticleDOI
Reduction Kinetics of Graphene Oxide Determined by Electrical Transport Measurements and Temperature Programmed Desorption
Inhwa Jung,Daniel Field,Nick Clark,Yanwu Zhu,Dongxing Yang,Richard D. Piner,Sasha Stankovich,Dmitriy A. Dikin,Heike Geisler,Carl A. Ventrice,Rodney S. Ruoff +10 more
TL;DR: The thermal stability and reduction kinetics of graphene oxide were studied by measuring the electrical resistivity of single-layer graphene films at various stages of reduction in high vacuum and by performing temperature programmed desorption (TPD) measurements of multilayer films in ultrahigh vacuum.
Journal ArticleDOI
Stable reconstruction of the polar (111) surface of NiO on Au(111).
TL;DR: In this paper, the authors demonstrate that deposition of Ni in an oxygen atmosphere onto a Au(111) substrate held at T \ensuremath{\sim}300 \ifmmode^\circ\else\text degree\fi{}C results in the growth of a stable p(2\ifmmodes\times\else \texttimes\fi {}2) reconstructed NiO(111), and resolve the atomic details of this surface with a scanning tunneling microscope.
Journal ArticleDOI
Electronic surface state of NiO (100)
A. Freitag,Volker Staemmler,D. Cappus,Carl A. Ventrice,K. Al Shamery,Helmut Kuhlenbeck,Hans-Joachim Freund +6 more
TL;DR: In this article, the electronic structure of the surface of NiO has been studied using EELS (electron energy loss spectroscopy) and ab initio calculations and two new states at energies of 0.57 and 1.62 eV have been found, attributed to d-d transitions of the nickel surface ions.
