Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…

Breakdown of the Chiral Anomaly in Weyl Semimetals in a Strong Magnetic Field
Pilkwang Kim, Ji Hoon Ryoo, Cheol-Hwan Park
The low-energy quasiparticles of Weyl semimetals are a condensed-matter realization of the Weyl fermions introduced in relativistic field theory. Chiral anomaly, the nonconservatio…

Spin-conserving and reversing photoemission from the surface states of BiSe and Au (111)
Ji Hoon Ryoo, Cheol-Hwan Park
We present a theory based on first-principles calculations explaining (i) why the tunability of spin polarizations of photoelectrons from BiSe (111) depends on the band ind…
