Band alignment estimation of MoS2/g-C3N4 thin-film S-scheme heterojunction based on surface potential measurements [PDF]
RSC Applied InterfacesEnergy band alignment of a thin-film heterojunction of molybdenum disulfide (MoS2) and polymeric carbon nitride (g-C3N4) has been investigated, and can be regarded as a model system of heterojunction photocatalysts.

Diffusion of Pb on Si studied by SFM and KPFM
Nanostructuring of surfaces, self-organization of structures and low dimensional systems are just a few points for which a precise understanding of diffusion, in particular surface diffusion, is important [1, 2, 3]. Pb/Si(111)-(7 × 7) exhibits unexpectedly fast diffusion.

Routes to rupture and folding of graphene on rough 6H-SiC(0001) and their identification
Beilstein Journal of Nanotechnology, 2013 Twisted few layer graphene (FLG) is highly attractive from an application point of view, due to its extraordinary electronic properties. In order to study its properties, we demonstrate and discuss three different routes to in situ create and identify ...

Direct measurement of protein dipoles reveals the mechanism for like-charge adsorption on silica
Nature CommunicationsNegatively charged particles are expected to adsorb with difficulty onto negatively charged surfaces. However, some proteins do. In this work, we use ferritin as a model protein particle to study its adsorption onto a negatively charged silica surface ...
