Journal ArticleDOI
Structural Attributes and Photodynamics of Visible Spectrum Quantum Emitters in Hexagonal Boron Nitride
Nathan Chejanovsky,Nathan Chejanovsky,Mohammad Rezai,Federico Paolucci,Youngwook Kim,Torsten Rendler,Wafa Rouabeh,Felipe Fávaro de Oliveira,Patrick Herlinger,Andrej Denisenko,Sen Yang,Ilja Gerhardt,Ilja Gerhardt,Amit Finkler,Jurgen H. Smet,Jörg Wrachtrup,Jörg Wrachtrup +16 more
TL;DR: This paper investigates correlations between h-BN structural features and emitter location from bulk down to the monolayer at room temperature and analyzes the emitters' spectral features to show that they are dominated by the interaction of their electronic transition with a single Raman active mode of h-bn.
Journal ArticleDOI
Copper-vapor-assisted chemical vapor deposition for high-quality and metal-free single-layer graphene on amorphous SiO2 substrate.
Hyungki Kim,Intek Song,Chibeom Park,Minhyeok Son,Misun Hong,Youngwook Kim,Jun Sung Kim,Hyun-Joon Shin,Jaeyoon Baik,Hee Cheul Choi +9 more
TL;DR: This method has overcome two important hurdles previously present when the catalyst-free CVD process is used for the growth of SLG on fused quartz and hexagonal boron nitride substrates, that is, high degree of structural defects and limited size of resulting graphene, respectively.
Journal ArticleDOI
Charge Inversion and Topological Phase Transition at a Twist Angle Induced van Hove Singularity of Bilayer Graphene
Youngwook Kim,Patrick Herlinger,Pilkyung Moon,Mikito Koshino,Takashi Taniguchi,Kenji Watanabe,Jurgen H. Smet +6 more
TL;DR: Here the authors have addressed magnetotransport when the chemical potential crosses the twist angle induced VHS in twisted bilayer graphene.
Journal ArticleDOI
Single-spin resonance in a van der Waals embedded paramagnetic defect.
Nathan Chejanovsky,Nathan Chejanovsky,Amlan Mukherjee,Jianpei Geng,Yu-Chen Chen,Youngwook Kim,Youngwook Kim,Andrej Denisenko,Amit Finkler,Takashi Taniguchi,Kenji Watanabe,Durga Bhaktavatsala Rao Dasari,Philipp Auburger,Adam Gali,Jurgen H. Smet,Jörg Wrachtrup,Jörg Wrachtrup +16 more
TL;DR: In this paper, a set of isolated optical emitters embedded in hexagonal boron nitride that exhibit optically detected magnetic resonance is reported. But the properties of these single-photon emitters are unknown.
Journal ArticleDOI
Breakdown of the interlayer coherence in twisted bilayer graphene.
Youngwook Kim,Hoyeol Yun,Seung-Geol Nam,Minhyeok Son,Dong Su Lee,Dong Chul Kim,Sunae Seo,Hee Cheul Choi,Hu-Jong Lee,Sangwook Lee,Jun Sung Kim +10 more
TL;DR: It is reported that complete suppression of coherent conduction is realized even in an atomic length scale of layer separation in twisted bilayer graphene, suggesting that the graphene layers are significantly decoupled by rotation and incoherent Conduction is a main transport channel between the layers of twisted bilayers graphene.
