Manipulating Hubbard-type Coulomb blockade effect of metallic wires embedded in an insulator
Xing Yang, Huimin Wang, Jing-Jing Xian +11
Correlated states emerge in low-dimensional systems owing to enhanced Coulomb interactions. Elucidating these states requires atomic scale characterization and delicate control cap…
Mott insulator tuning via structural distortion in monolayer 1T-NbSe2
Zhen-Yu Liu, Shuang Qiao, Qiao-Yin Tang +8
Mott state in 1T-TaS2 is predicted to host quantum spin liquids (QSL). However, its insulating mechanism is controversial due to complications from interlayer coupling. Here, we st…

Possible phason-polaron effect on purely one dimensional charge order of Mo6Se6 nanowires
Xing Yang, Jing-Jing Xian, Gang Li +6
In one-dimensional (1D) metallic systems, the diverging electron susceptibility and electron-phonon coupling collaboratively drive the electrons into a charge density wave (CDW) st…
Mott phase in a van der Waals transition-metal halide at single layer limit
Lang Peng, Jianzhou Zhao, Gui-Yuan Hua +9
Two-dimensional materials offer opportunities for unravelling unprecedented ordered states at single layer limit. Among such ordered states, Mott phase is rarely explored. Here, we…
