Orbitally controlled quantum Hall states in decoupled two-bilayer graphene sheets
Soyun Kim, Dohun Kim, Kenji Watanabe +3
We report on integer and fractional quantum Hall states in a stack of two twisted Bernal bilayer graphene sheets. By exploiting the momentum mismatch in reciprocal space, we suppre…
Fresnel-type Solid Immersion Lens for efficient light collection from quantum defects in diamond
SungJoon Park, Gyeonghun Kim, Kiho Kim +1
Quantum defects in diamonds have been studied as a promising resource for quantum science. The subtractive fabrication process for improving photon collection efficiency often requ…
Observation of Electronic Modes in Open Cavity Resonator
Hwanchul Jung, Dongsung T. Park, Seokyeong Lee +9
The resemblance between electrons and optical waves has strongly driven the advancement of mesoscopic physics. However, electron waves have yet to be understood in open cavity stru…
Robust Interlayer-Coherent Quantum Hall States in Twisted Bilayer Graphene
Dohun Kim, Byungmin Kang, Yong-Bin Choi +5
We introduce a novel two-dimensional electronic system with ultrastrong interlayer interactions, namely twisted bilayer graphene with a large twist angle, as an ideal ground for re…
Defect Passivation of 2D Semiconductors by Fixating Chemisorbed Oxygen Molecules via h-BN Encapsulations
Jin-Woo Jung, Hyeon-Seo Choi, Young-Jun Lee +9
Hexagonal boron nitride (h-BN) is a key ingredient for various two-dimensional (2D) van der Waals heterostructure devices, but the exact role of h-BN encapsulation in relation to t…
Wigner-molecularization-enabled dynamic nuclear field programming
Wonjin Jang, Jehyun Kim, Jaemin Park +8
Multielectron semiconductor quantum dots (QDs) provide a novel platform to study the role of Coulomb correlations in finite quantum systems and their impact on many-body energy spe…
