Ferroelectric Quantum Point Contact in Twisted Transition Metal Dichalcogenides
Wei Ren, Shiyu Guo, Daochen Long +8
In twisted transition metal dichalcogenides (tTMDs), atomic reconstruction gives rise to moiré domains with alternating ferroelectric polarization, whose domain size and overall el…

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…

Visualizing topological edge states of single and double bilayer Bi supported on multibilayer Bi(111) films
Lang Peng, Jing-Jing Xian, Peizhe Tang +4
Freestanding single-bilayer Bi(111) is a two-dimensional topological insulator with edge states propagating along its perimeter. Given the interlayer coupling experimentally, the t…
