Bulk and edge dynamics of a 2D Affleck-Kennedy-Lieb-Tasaki model
Zenan Liu, Jun Li, Rui-Zhen Huang +2
We study the dynamical properties of both bulk and edge spins of a two-dimensional Affleck-Kennedy-Lieb-Tasaki (AKLT) model mainly by using the stochastic series expansion quantum…
Enhanced spin-orbit coupling and orbital moment in ferromagnets by electron correlations
Ze Liu, Jing-Yang You, Bo Gu +2
In atomic physics, the Hund rule says that the largest spin and orbital state is realized due to the interplay of the spin-orbit coupling (SOC) and the Coulomb interactions. Here,…
Mechanical buckling induced periodic kinking/stripe microstructures in mechanically peeled graphite flakes from HOPG
Manrui Ren, Ze Liu, Quan-shui Zheng +1
Mechanical exfoliation is a widely used method to isolate high quality graphene layers from bulk graphite. In our recent experiments, some ordered microstructures, consisting of a…
Binding and interlayer force in the near-contact region of two graphite slabs: experiment and theory
Tim Gould, Ze Liu, Jefferson Zhe Liu +3
Via a novel experiment, Liu \emph{et al.} [Phys. Rev. B, {\bf 85}, 205418 (2012)] estimated the graphite binding energy, specifically the cleavage energy, an important physical pro…
Interlayer shear strength of single crystalline graphite
Ze Liu, Shoumo Zhang, Jiarui Yang +3
Reported values (0.2 MPa ~ 7.0 GPa) of the interlayer shear strength (ISS) of graphite are very dispersed. The main challenge to obtain a reliable value of ISS is the lack of preci…
Self-retracting motion of graphite micro-flakes: superlubricity in micrometer scale
Ze Liu, Jefferson Zhe Liu, Jiarui Yang +4
Through experimental study, we reveal superlubricity as the mechanism of self-retracting motion of micrometer sized graphite flakes on graphite platforms by correlating respectivel…
Interlayer binding energy of graphite -- A direct experimental determination
Ze Liu, Jefferson Zhe Liu, Yao Cheng +1
Despite interlayer binding energy is one of the most important material properties for graphite, there is still lacking report on its direct experimental determination. In this pap…
Graphite Nanoeraser
Ze Liu, Peter. Bøggild, Jia-rui Yang +5
We present here a method for cleaning intermediate-size (5~50nm) contamination from highly oriented pyrolytic graphite. Electron beam deposition causes a continuous increase of car…
