Journal ArticleDOI
Atomic structure and electronic properties of single-walled carbon nanotubes
TL;DR: In this paper, the structure and electronic properties of single-walled carbon nanotubes (SWNTs) were investigated using tunnelling microscopy, and it was shown that the SWNT samples exhibit many different structures, with no one species dominating.
Journal ArticleDOI
Atomically thin p–n junctions with van der Waals heterointerfaces
Chul Ho Lee,Chul Ho Lee,Gwan Hyoung Lee,Arend M. van der Zande,Wenchao Chen,Yilei Li,Minyong Han,Xu Cui,Ghidewon Arefe,Colin Nuckolls,Tony F. Heinz,Jing Guo,James Hone,Philip Kim +13 more
TL;DR: The tunnelling-assisted interlayer recombination of the majority carriers is responsible for the tunability of the electronic and optoelectronic processes in atomically thin p-n heterojunctions fabricated using van der Waals assembly of transition-metal dichalcogenides.
Journal ArticleDOI
Current saturation in zero-bandgap, top-gated graphene field-effect transistors.
TL;DR: The first observation of saturating transistor characteristics in a graphene field-effect transistor is reported, demonstrating the feasibility of two-dimensional graphene devices for analogue and radio-frequency circuit applications without the need for bandgap engineering.
Journal ArticleDOI
Thermal conductivity of individual silicon nanowires
TL;DR: The thermal conductivities of individual single crystalline intrinsic Si nanowires with diameters of 22, 37, 56, and 115 nm were measured using a microfabricated suspended device over a temperature range of 20-320 K as discussed by the authors.
Journal ArticleDOI
Hofstadter’s butterfly and the fractal quantum Hall effect in moiré superlattices
Cory Dean,Lei Wang,Patrick Maher,Carlos Forsythe,Fereshte Ghahari,Yuanda Gao,Jyoti Katoch,Masa Ishigami,Pilkyung Moon,Mikito Koshino,Takashi Taniguchi,Kenji Watanabe,Kenneth L. Shepard,James Hone,Philip Kim +14 more
TL;DR: It is demonstrated that moiré superlattices arising in bilayer graphene coupled to hexagonal boron nitride provide a periodic modulation with ideal length scales of the order of ten nanometres, enabling unprecedented experimental access to the fractal spectrum.
