Journal ArticleDOI
Coulomb blockade and the Kondo effect in single-atom transistors
Jiwoong Park,Jiwoong Park,Abhay Pasupathy,Jonas I. Goldsmith,Connie Chang,Yuval Yaish,Jason R. Petta,Marie Rinkoski,James P. Sethna,Héctor D. Abruña,Paul L. McEuen,Daniel C. Ralph +11 more
TL;DR: Two related molecules containing a Co ion bonded to polypyridyl ligands, attached to insulating tethers of different lengths are examined, enabling the fabrication of devices that exhibit either single-electron phenomena, such as Coulomb blockade or the Kondo effect.
Journal ArticleDOI
Grains and grain boundaries in single-layer graphene atomic patchwork quilts
Pinshane Y. Huang,Carlos Ruiz-Vargas,Arend M. van der Zande,William S. Whitney,Mark Levendorf,Joshua W. Kevek,Shivank Garg,Jonathan S. Alden,Caleb Hustedt,Ye Zhu,Jiwoong Park,Paul L. McEuen,David A. Muller +12 more
TL;DR: This work determines the location and identity of every atom at a grain boundary and finds that different grains stitch together predominantly through pentagon–heptagon pairs, and reveals an unexpectedly small and intricate patchwork of grains connected by tilt boundaries.
Journal ArticleDOI
The valley Hall effect in MoS2 transistors
TL;DR: The observation of the so-called valley Hall effect in a monolayer of MoS2 opens up new possibilities for using the valley DOF as an information carrier in next-generation electronics and optoelectronics.
Journal ArticleDOI
Nanomechanical oscillations in a single-C60 transistor
Hongkun Park,Hongkun Park,Jiwoong Park,Andrew K. L. Lim,Erik H. Anderson,A. Paul Alivisatos,Paul L. McEuen,Paul L. McEuen +7 more
TL;DR: Transport measurements are performed that provide evidence for a coupling between the centre-of-mass motion of the C60 molecules and single-electron hopping—a conduction mechanism that has not been observed previously in quantum dot studies.
Journal ArticleDOI
High-mobility three-atom-thick semiconducting films with wafer-scale homogeneity
Kibum Kang,Saien Xie,Lujie Huang,Yimo Han,Pinshane Y. Huang,Kin Fai Mak,Cheol-Joo Kim,David A. Muller,Jiwoong Park +8 more
TL;DR: The preparation of high-mobility 4-inch wafer-scale films of monolayer molybdenum disulphide and tungsten disulPHide, grown directly on insulating SiO2 substrates, with excellent spatial homogeneity over the entire films are reported, a step towards the realization of atomically thin integrated circuitry.
