Geliang Yu,Rashid Jalil,Branson D. Belle,A. S. Mayorov,Peter Blake,Fred Schedin,Sergey V. Morozov,Leonid Ponomarenko,F. Chiappini,Steffen Wiedmann,Uli Zeitler,Mikhail I. Katsnelson,Andre K. Geim,Kostya S. Novoselov,D. C. Elias +14 more
TL;DR: Large-area high-quality graphene capacitors are used to study behavior of the density of states in this material in zero and high magnetic fields, revealing a number of interesting many-body effects.
Journal ArticleDOI
Probing the surface states in bi2se3 using the shubnikov-de haas effect
M. Petrushevsky,E. Lahoud,A. Ron,Eran Maniv,I. Diamant,Izhar Neder,Steffen Wiedmann,V. K. Guduru,F. Chiappini,Uli Zeitler,Jan C. Maan,K. B. Chashka,Amit Kanigel,Yoram Dagan +13 more
TL;DR: Shubnikov-de Haas oscillations are observed in Bi{}_{2}$Se${}_{3}$ flakes with high carrier concentration and low bulk mobility as discussed by the authors.
Journal ArticleDOI
Lifting of the Landau level degeneracy in graphene devices in a tilted magnetic field
F. Chiappini,Steffen Wiedmann,Kostya S. Novoselov,Artem Mishchenko,Andre K. Geim,Jan C. Maan,Uli Zeitler +6 more
TL;DR: In this paper, the authors report on transport and capacitance measurements of graphene devices in magnetic fields up to 30 T and observe the full splitting of Landau levels and employ tilted field experiments to address the origin of the observed broken symmetry states.
Journal ArticleDOI
Magnetotransport in single-layer graphene in a large parallel magnetic field
F. Chiappini,Steffen Wiedmann,Mikhail Titov,Andre K. Geim,Roman V. Gorbachev,Ekaterina Khestanova,Artem Mishchenko,Kostya S. Novoselov,Jan C. Maan,Uli Zeitler +9 more
TL;DR: In this article, the effect of Zeeman splitting on electron transport on hexagonal boron nitride (h-BN) was investigated using magnetotransport measurements and it was shown that a parallel magnetic field up to 30 Tesla does not affect the transport properties of graphene on h-BN.
Proceedings ArticleDOI
Monitoring the Laser Metal Deposition (LMD) process by means of thermal methods
E. D’Accardi,F. Chiappini,A. Giannasi,Mirco Guerrini,Gianluca Maggiani,Davide Palumbo,Umberto Galietti +6 more
TL;DR: In this paper , the capability of thermography to detect anomalies with the analysis of statistical indexes and thermal features has been evaluated and the possibility to correlate thermal features and process parameters has been demonstrated by means of an ANOVA analysis(Analysis of Variance)and regression models, considering experimental plans that involved the use of different parameters in terms of power, scanning speed, and powder flow rate.
