Robust edge photocurrent response on layered type II Weyl semimetal WTe2
Novel optoelectronic properties have recently been observed in topological semimetals. Here, Wang et al. report a robust photocurrent generated from charge separation of photoexcited electron-hole pairs at the edge of a type-II Weyl semimetal, T d-WTe2.
