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.
Journal ArticleDOI
Electron ptychography of 2D materials to deep sub-ångström resolution
Yi Jiang,Zhen Chen,Yimo Han,Pratiti Deb,Hui Gao,Hui Gao,Saien Xie,Saien Xie,Prafull Purohit,Mark W. Tate,Jiwoong Park,Sol M. Gruner,Veit Elser,David A. Muller +13 more
TL;DR: This ptychographic reconstruction improves the image contrast of single-atom defects in MoS2 substantially, reaching an information limit close to 5α, which corresponds to an Abbe diffraction-limited resolution of 0.39 ångström.
Journal ArticleDOI
Layer-by-layer assembly of two-dimensional materials into wafer-scale heterostructures
Kibum Kang,Kan-Heng Lee,Yimo Han,Hui Gao,Hui Gao,Saien Xie,Saien Xie,David A. Muller,Jiwoong Park +8 more
TL;DR: The generation of wafer-scale semiconductor films with a very high level of spatial uniformity and pristine interfaces is reported, designed at the atomic scale using layer-by-layer assembly of two-dimensional building blocks under vacuum.
Journal ArticleDOI
Coherent, atomically thin transition-metal dichalcogenide superlattices with engineered strain
Saien Xie,Saien Xie,Lijie Tu,Yimo Han,Lujie Huang,Kibum Kang,Ka Un Lao,Preeti Poddar,Chibeom Park,David A. Muller,Robert A. DiStasio,Jiwoong Park,Jiwoong Park +12 more
TL;DR: Report of coherent atomically thin superlattices in which different transition metal dichalcogenide monolayers—despite large lattice mismatches—are repeated and laterally integrated without dislocations within the monolayer plane.
Journal ArticleDOI
Atomically Thin Ohmic Edge Contacts Between Two-Dimensional Materials
Marcos H. D. Guimarães,Hui Gao,Yimo Han,Kibum Kang,Saien Xie,Cheol-Joo Kim,David A. Muller,Daniel C. Ralph,Jiwoong Park +8 more
TL;DR: A scalable method to fabricate ohmic graphene edge contacts to two representative monolayer TMDs, MoS2 and WS2, which show linear current-voltage characteristics at room temperature, with ohmic behavior maintained down to liquid helium temperatures.
