Journal ArticleDOI
An atomic-resolution nanomechanical mass sensor.
TL;DR: This work demonstrates a room-temperature, carbon-nanotube-based nanomechanical resonator with atomic mass resolution, and observes atomic mass shot noise, analogous to the electronic shot noise measured in many semiconductor experiments.
Journal ArticleDOI
High-resolution EM of colloidal nanocrystal growth using graphene liquid cells
Jong Min Yuk,Jong Min Yuk,Jong Min Yuk,Jungwon Park,Jungwon Park,Peter Ercius,Kwanpyo Kim,Kwanpyo Kim,Daniel J. Hellebusch,Michael F. Crommie,Michael F. Crommie,Jeong Yong Lee,Alex Zettl,Alex Zettl,A. Paul Alivisatos,A. Paul Alivisatos +15 more
TL;DR: A new type of liquid cell for in situ transmission electron microscopy (TEM) based on entrapment of a liquid film between layers of graphene that facilitates atomic-level resolution imaging while sustaining the most realistic liquid conditions achievable under electron-beam radiation is introduced.
Journal ArticleDOI
Grain Boundary Mapping in Polycrystalline Graphene
Kwanpyo Kim,Zonghoon Lee,Zonghoon Lee,William Regan,Christian Kisielowski,Michael F. Crommie,Alex Zettl +6 more
TL;DR: Direct mapping of the grains and grain boundaries (GBs) of large-area monolayer polycrystalline graphene sheets, at large (several micrometer) and single-atom length scales is reported, which provides a readily adaptable tool for graphene GB studies.
Journal ArticleDOI
Highly Skin‐Conformal Microhairy Sensor for Pulse Signal Amplification
Changhyun Pang,Changhyun Pang,Ja Hoon Koo,Amanda Nguyen,Jeffrey M. Caves,Myung-Gil Kim,Myung-Gil Kim,Alex Chortos,Kwanpyo Kim,Kwanpyo Kim,Paul J. Wang,Jeffrey B.-H. Tok,Zhenan Bao +12 more
TL;DR: A bioinspired microhairy sensor is developed to enable ultraconformability on nonflat surfaces and significant enhancement in the signal-to-noise ratio of the retrieved signals.
Journal ArticleDOI
Raman spectroscopy study of rotated double-layer graphene: misorientation-angle dependence of electronic structure.
Kwanpyo Kim,Kwanpyo Kim,Sinisa Coh,Sinisa Coh,Liang Z. Tan,Liang Z. Tan,William Regan,William Regan,Jong Min Yuk,Jong Min Yuk,Jong Min Yuk,Eric Chatterjee,Michael F. Crommie,Michael F. Crommie,Marvin L. Cohen,Marvin L. Cohen,Steven G. Louie,Steven G. Louie,Alex Zettl,Alex Zettl +19 more
TL;DR: A systematic Raman study of unconventionally stacked double-layer graphene finds that the spectrum strongly depends on the relative rotation angle between layers, and reveals changes in electronic band structure due to the interlayer interaction are responsible for the observed spectral features.
