Recently, a research team led by Professor Wang Zhe, the School of Physics at Xi'an Jiaotong University (XJTU), demonstrated that through numerical simulations, bent bilayer graphene structures can overcome slip barriers and achieve energy-stable interlayer sliding.

Further theoretical analysis revealed that this sliding can induce a reversal of the Berry curvature, thereby realizing topological edge states in a one-dimensional moiré channel.

In terms of experimentation, the research team transferred the bilayer graphene to a nano-ridge structured substrate, achieving effective control of the interlayer sliding. Low-temperature electronic transport measurements clearly showed topological transport behavior within the band gap.

Through a systematic study of the dependence of saturation conductance on channel length, the team revealed the existence of eight quantum channels in the system. The experimental measurements aligned with theoretical calculations, providing experimental evidence for the realization and control of interlayer sliding.

The related findings, titled Topological valley transport in bilayer graphene induced by interlayer sliding, were published in the journal Physical Review Letters and were also selected as an Editor's Suggestion and featured in Physics Magazine, the official online magazine of the American Physical Society.
