Journal ArticleDOI
Chiral atomically thin films
Cheol-Joo Kim,A. Sánchez-Castillo,Zack Ziegler,Yui Ogawa,Yui Ogawa,Cecilia Noguez,Jiwoong Park +6 more
TL;DR: A chiral stacking approach, where two-dimensional materials are positioned layer-by-layer with precise control of the interlayer rotation and polarity, resulting in tunable chiral properties of the final stack, which produces a two-atom-thick chiral film.
Journal ArticleDOI
Vibration-Assisted Electron Tunneling in C140 Transistors
Abhay Pasupathy,Jiwoong Park,C. Chang,Alexander Soldatov,S. Lebedkin,R. C. Bialczak,J. E. Grose,L. A. K. Donev,James P. Sethna,Daniel C. Ralph,P. L. McEuen +10 more
TL;DR: Comparisons are made between the observed tunneling rates and those expected from the Franck-Condon model and molecular modeling provides explanations for why this mode couples more strongly to electron tunneling than to the other internal modes of the molecule.
Journal ArticleDOI
Klein tunnelling and electron trapping in nanometre-scale graphene quantum dots
TL;DR: Relativistic Dirac fermions can be locally confirmed in nanoscale graphene quantum dots using electrostatic gating, and directly imaged using scanning-tuning microscopy before escaping via Klein tunnelling as mentioned in this paper.
Journal ArticleDOI
Stacking Order Dependent Second Harmonic Generation and Topological Defects in h-BN Bilayers
Cheol-Joo Kim,Lola Brown,Matt W. Graham,Robert Hovden,Robin W. Havener,Paul L. McEuen,David A. Muller,Jiwoong Park +7 more
TL;DR: A strong correlation between the interlayer stacking structures and optical and topological properties in chemically grown h-BN bilayers is reported, measured mainly by using dark-field transmission electron microscopy (DF-TEM) and optical second harmonic generation (SHG) mapping.
Journal ArticleDOI
Wafer-scale synthesis of monolayer two-dimensional porphyrin polymers for hybrid superlattices
Yu Zhong,Baorui Cheng,Chibeom Park,Ariana Ray,Sarah Brown,Fauzia Mujid,Jae-Ung Lee,Jae-Ung Lee,Hua Zhou,Joonki Suh,Kan-Heng Lee,Kan-Heng Lee,Andrew J. Mannix,Kibum Kang,Kibum Kang,Steven J. Sibener,David A. Muller,Jiwoong Park +17 more
TL;DR: The synthesis of two-dimensional (2D) porphyrin polymer films with wafer-scale homogeneity in the ultimate limit of monolayer thickness by growing films at a sharp pentane/water interface, which allows the fabrication of their hybrid superlattices.
