Journal ArticleDOI
Part-per-million quantization and current-induced breakdown of the quantum anomalous Hall effect
Eli Fox,Eli Fox,Ilan Rosen,Ilan Rosen,Yanfei Yang,George R. Jones,Randolph E. Elmquist,Xufeng Kou,Xufeng Kou,Lei Pan,Kang L. Wang,David Goldhaber-Gordon,David Goldhaber-Gordon +12 more
TL;DR: In this article, the authors explore the potential of the quantum anomalous Hall effect in magnetic topological insulator thin films for metrological applications and find evidence for bulk dissipation, including thermal activation and possible variable-range hopping.
Journal ArticleDOI
Low Carrier Density Epitaxial Graphene Devices On SiC
Yanfei Yang,Yanfei Yang,Lung-I Huang,Lung-I Huang,Yasuhiro Fukuyama,Fan-Hung Liu,Mariano A. Real,Paola Barbara,Chi-Te Liang,David B. Newell,Randolph E. Elmquist +10 more
TL;DR: In this article, the transport characteristics of graphene devices with low n- or p-type carrier density (∼10(10) -10(11) cm(-2) ), fabricated using a new process that results in minimal organic surface residues, are reported.
Journal ArticleDOI
Electrical properties and memory effects of field-effect transistors from networks of single- and double-walled carbon nanotubes.
Antonio Di Bartolomeo,Antonio Di Bartolomeo,M. B. M. Rinzan,Anthony K. Boyd,Yanfei Yang,Liberata Guadagno,Filippo Giubileo,Paola Barbara +7 more
TL;DR: It is shown that charge storage can be improved by limiting exposure of the device to air and water enhanced charge trapping at the SiO(2)/air interface close to the nanotubes is proposed as the dominant mechanism for charge storage.
Journal ArticleDOI
Epitaxial graphene homogeneity and quantum Hall effect in millimeter-scale devices
Yanfei Yang,Guangjun Cheng,Patrick C. Mende,Irene Calizo,Randall M. Feenstra,Chiashain Chuang,Chieh-Wen Liu,Chieh-I Liu,George R. Jones,Angela R. Hight Walker,Randolph E. Elmquist +10 more
TL;DR: In this paper, the structural uniformity of epitaxial graphene produced by face-to-graphite processing contributes to millimeter-scale transport homogeneity, and will prove useful for scientific and commercial applications.
Journal ArticleDOI
