Crystallographic orientation errors in mechanical exfoliation
Y. Kolumbus, A. Zalic, N. Fardian-Melamed +4
We evaluate the effect of mechanical exfoliation of van der Waals materials on crystallographic orientations of the resulting flakes. Flakes originating from a single crystal of gr…
Comparative Electrostatic Force Microscopy of Tetra- and Intra-Molecular G4-DNA
Gideon I. Livshits, Jamal Ghabboun, Natalia Borovok +2
Two forms of G4-DNA, with parallel and pairwise anti-parallel strands, are studied using atomic force microscopy. The directionality of the strands affects the molecules' structura…
Inelastic quantum transport in a ladder model: Measurements of DNA conduction and comparison to theory
R. Gutierrez, S. Mohapatra, H. Cohen +2
We investigate quantum transport characteristics of a ladder model, which effectively mimics the topology of a double-stranded DNA molecule. We consider the interaction of tunnelin…
Charge Transport in DNA-Based Devices
Danny Porath, Gianaurelio Cuniberti, Rosa Di Felice
Charge migration along DNA molecules has attracted scientific interest for over half a century. Reports on possible high rates of charge transfer between donor and acceptor through…
Tight binding description of the STM image of molecular chains
Yoel Calev, Hezy Cohen, Gianaurelio Cuniberti +2
A tight binding model for scanning tunneling microscopy images of a molecule adsorbed on a metal surface is described. The model is similar in spirit to that used to analyze conduc…
Backbone-induced semiconducting behavior in short DNA wires
G. Cuniberti, L. Craco, D. Porath +1
We propose a model Hamiltonian for describing charge transport through short homogeneous double stranded DNA molecules. We show that the hybridization of the overlapping pi orbital…
