Effects of Partial Hydrogenation on the Structure and Electronic Properties of BNNTs
Lena Kalikhman-Razvozov, Roza Yusupov, Oded Hod
The effects of partial hydrogenation on the structure and electronic properties of boron nitride nanotubes are investigated via density functional theory calculations. We find that…
Robust Superlubricity in Graphene/h-BN Heterojunctions
Itai Leven, Dana Krepel, Ortal Shemesh +1
The sliding energy landscape of the heterogeneous graphene/h-BN interface is studied by means of the registry index. For a graphene flake sliding on top of h-BN the anisotropy of t…
Structural stability and electronic properties of SP3 type silicon nanotubes
Alon Hever, Jonathan Bernstein, Oded Hod
A density functional theory study of the structural and electronic properties and relative stability of narrow SP3 silicon nanotubes of different growth orientations is presented.…
Interlayer Registry Determines the Sliding Potential of Layered Metal Dichalcogenides: The case of 2H-MoS2
Adi Blumberg, Uri Keshet, Inbal Zaltsman +1
We provide a simple and intuitive explanation for the interlayer sliding energy landscape of metal dichalcogenides. Based on the recently introduced registry index (RI) concept, we…
Superlubricity - a new perspective on an established paradigm
Oded Hod
Superlubricity is a frictionless tribological state sometimes occurring in nanoscale material junctions. It is often associated with incommensurate surface lattice structures appea…
