Surface Reconstruction-Driven Insulating Behavior in Metallic Charge-Density-Wave 1T-TaSe
Sung-Hoon Lee, Doohee Cho
Bulk 1T-TaSe is metallic, yet its surface consistently exhibits an insulating gap -- a dichotomy long attributed to a surface Mott insulator driven by enhanced electron correla…
Transparency-controlled multiple charge transfer in superconducting junctions with local shot-noise scanning tunneling spectroscopy
Yudai Sato, Maialen Ortego Larrazabal, Jian-Feng Ge +6
Charge transport in superconducting junctions at finite voltages is governed by Andreev reflections, including multiple Andreev reflections, which are processes that enable multipl…
Imaging asymmetric Coulomb blockade phenomena across metallic nanoislands
Junho Bang, Byeongin Lee, Hankyu Lee +2
Coulomb blockade (CB) arises in nanoscale systems with ultra-small capacitance, where discrete charging effects dictate electron transport, enabling wide-ranging applications based…
Identifying field-tunable surface resonance states on black phosphorus
Dongming Zhao, Byeongin Lee, Junho Bang +3
Surface resonance states are electronic states localized near the surface while remaining hybridized with bulk bands. These states can strongly modify the electric-field response o…
Anomalous impurity-induced charge modulations in black phosphorus
Byeongin Lee, Junho Bang, Sayan Banerjee +6
We observe anomalous charge modulations induced by ionized indium impurities on the surface of the semiconductor black phosphorus by scanning tunneling microscopy (STM). When the i…
Charge ordered phases in the hole-doped triangular Mott insulator 4Hb-TaS2
Junho Bang, Byeongin Lee, Hyungryul Yang +3
4Hb-TaS2 has been proposed to possess unconventional superconductivity with broken time reveral symmetry due to distinctive layered structure, featuring a heterojunction between a…
Origin of Distinct Insulating Domains in the Layered Charge Density Wave Material 1T-TaS2
Hyungryul Yang, Byeongin Lee, Junho Bang +4
Vertical charge order shapes the electronic properties in layered charge density wave (CDW) materials. Various stacking orders inevitably create nanoscale domains with distinct ele…
Melting of unidirectional charge density waves across twin domain boundaries in GdTe
Sanghun Lee, Eunseo Kim, Junho Bang +4
Solids undergoing a transition from order to disorder experience the proliferation of topological defects. The melting process generates transient quantum states. However, their dy…
