Journal ArticleDOI
Single-layer MoS2 nanopores as nanopower generators
Jiandong Feng,Michael Graf,Ke Liu,Dmitry Ovchinnikov,Dumitru Dumcenco,Mohammad Heiranian,Vishal Nandigana,Narayana R. Aluru,Andras Kis,Aleksandra Radenovic +9 more
TL;DR: A large, osmotically induced current is observed produced from a salt gradient with an estimated power density of up to 106 watts per square metre—a current that can be attributed mainly to the atomically thin membrane of MoS2, thus demonstrating a self-powered nanosystem.
Journal ArticleDOI
Atomically Thin Molybdenum Disulfide Nanopores with High Sensitivity for DNA Translocation
TL;DR: It is demonstrated that monolayer or few-layer thick exfoliated MoS2 with subnanometer thickness can be transferred and suspended on a predesigned location on the 20 nm thick SiNx membranes, implying that MoS 2 membranes with nanopore can complement graphene nanopore membranes and offer potentially better performance in transverse detection.
Journal ArticleDOI
Identification of single nucleotides in MoS2 nanopores
Jiandong Feng,Ke Liu,Roman D. Bulushev,Sergey Khlybov,Dumitru Dumcenco,Andras Kis,Aleksandra Radenovic +6 more
TL;DR: A viscosity gradient system based on room-temperature ionic liquids can be used to control the dynamics of DNA translocation through MoS2 nanopores and provides optimal single nucleotide translocation speeds for DNA sequencing, while maintaining a signal-to-noise ratio higher than 10.
Journal ArticleDOI
Detecting the translocation of DNA through a nanopore using graphene nanoribbons
Floriano Traversi,Camille Raillon,S. M. Benameur,Ke Liu,Sergey Khlybov,Mahmut Tosun,Daria Krasnozhon,Andras Kis,Aleksandra Radenovic +8 more
TL;DR: It is shown that a solid-state nanopore can be integrated with a graphene nanoribbon transistor to create a sensor for DNA translocation and the correlation between these two signals is examined.
Journal ArticleDOI
From tunneling to hopping: a comprehensive investigation of charge transport mechanism in molecular junctions based on oligo(p-phenylene ethynylene)s.
TL;DR: The charge transport mechanism of oligo(p-phenylene ethynylene)s with lengths ranging from 0.98 to 5.11 nm was investigated using modified scanning tunneling microscopy break junction and conducting probe atomic force microscopy methods, and an intrinsic transition from tunneling to hopping charge transport mechanisms was observed.
