Robustness and Universality of Surface States in Dirac Materials [PDF]

open access: yes, 2018
Ballistically propagating topologically protected states harbor exotic transport phenomena of wide interest. Here we describe a nontopological mechanism that produces such states at the surfaces of generic Dirac materials, giving rise to propagating ...

DSSC Anchoring Groups: A Surface Dependent Decision [PDF]

open access: yes, 2014
Electrodes in dye sensitised solar cells (DSSCs) are typically nanocrystalline anatase TiO2 with a majority (101) surface exposed. Generally the sensitising dye employs a carboxylic anchoring moiety through which it adheres to the TiO2 surface.
