Bulk Fermi arc transition induced large photogalvanic effect in Weyl semimetals
Bulk Fermi arc transition induced large photogalvanic effect in Weyl semimetals
The surface Fermi arc, as a hallmark of Weyl semimetals (WSMs), has been well known in current research, but it remains a challenge to unveil novel phenomena associated with the Fermi arc. Here, in WSMs, namely, the photoinduced transition between the bulk states and the Fermi arc. We find this …
