Query: Majorana Fermions on Zigzag Edge of Monolayer Transition Metal
  Dichalcogenides   Majorana fermions, quantum particles with non-Abelian exchange statistics,
are not only of fundamental importance, but also building blocks for
fault-tolerant quantum computation. Although certain experimental breakthroughs
for observing Majorana fermions have been made recently, their conclusive
dection is still challenging due to the lack of proper material properties of
the underlined experimental systems. Here we propose a new platform for
Majorana fermions based on edge states of certain non-topological
two-dimensional semiconductors with strong spin-orbit coupling, such as
monolayer group-VI transition metal dichalcogenides (TMD). Using
first-principles calculations and tight-binding modeling, we show that zigzag
edges of monolayer TMD can host well isolated single edge band with strong
spin-orbit coupling energy. Combining with proximity induced s-wave
superconductivity and in-plane magnetic fields, the zigzag edge supports robust
topological Majorana bound states at the edge ends, although the
two-dimensional bulk itself is non-topological. Our findings points to a
controllable and integrable platform for searching and manipulating Majorana
fermions.
