A new UHV preparation reveals that the rotated dense Ag(2) phase at graphene/SiC has distinct bands and dopes the graphene more strongly than the epitaxial Ag(1) phase.
Discovery via symmetry-guided ML of Netsene (bct-C24), a dynamically stable carbon allotrope exhibiting nested nodal-surface semimetal behavior with Dirac-like crossings and drumhead surface states.
In this non-degenerate mixture at charge neutrality, conductivity is temperature-independent at low T from Dirac carriers but acquires a negative correction from scattering with thermally excited massive holes that strengthens with temperature and is stronger for short-range interactions.

Interaction-driven transport in a non-degenerate mixture of Dirac and massive fermions at charge neutrality point
In this non-degenerate mixture at charge neutrality, conductivity is temperature-independent at low T from Dirac carriers but acquires a negative correction from scattering with thermally excited massive holes that strengthens with temperature and is stronger for short-range interactions.
