Query: Corrugation induced stacking solitons with topologically confined states
  in gapped bilayer graphene   Graphene, as an atomic-thick ultrasoft membrane, almost has no resistance
against out-of-plane deformations and, therefore, it is always wrinkled to a
certain degree. Recently, corrugated structures and their effects on the
electronic properties of monolayer graphene have been studied extensively.
However, similar experimental studies in bilayer graphene have yet to be
reported. Here, we show that corrugations in bilayer graphene can generate
incommensurate stacking solitons (domain walls) between commensurate
Bernal-stacked domains. By using scanning tunneling microscopy, we
microscopically study electronic structures of a corrugation-induced stacking
soliton that separates two adjacent AB and BA stacked bilayer regions with a
uniform interlayer potential difference. Both topological gapless edge states
and quasi-localized gapped quantum-well-like states are observed in the
nanoscale corrugation. Atomic resolution mapping of the topological edge states
along the stacking soliton reveals the existence of intervalley scattering
between them, which could explain recent experiments where the conductance
along domain walls of gapped graphene bilayer is smaller than a quantized value
4e2 h.
