Engineering Borophene Band Structure Through Thickness

Advanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...

Molecular Dynamics Study of Bending Deformation of Mo₂Ti₂C₃ and Ti₄C₃ (MXenes) Nanoribbons

Molecules
We report a computational study of the bending deformation of two-dimensional nanoribbons by classical molecular dynamics methods. Two-dimensional double transition metal carbides, together with monometallic ones, belong to the family of novel ...

Urethane tetrathiafulvalene derivatives: synthesis, self-assembly and electrochemical properties

Beilstein Journal of Organic Chemistry, 2015
This paper reports the self-assembly of two new tetrathiafulvalene (TTF) derivatives that contain one or two urethane groups. The formation of nanoribbons was evidenced by scanning electron microscopy (SEM) and X-ray diffraction (XRD), which showed that ...

Self‐Limited Switching Femtojoule‐Class RESET Energy Estimate in Deep‐Confine in‐Doped Sb2Te3 Phase‐Change Memory

Advanced Electronic Materials, EarlyView.
Pulsed electrodeposition enables cyclic Te‐terminated In/Sb incorporation to form composition‐uniform amorphous In‐doped Sb2Te3 for deep‐confine phase‐change memory. The resulting devices exhibit well‐separated resistance states and femtojoule‐class RESET energy statistics, highlighting a self‐limited low‐power switching route beyond conventional ...

Narrowband noise study of sliding charge density waves in NbSe3 nanoribbons

New Journal of Physics, 2017
Transport properties (dc electrical resistivity, threshold electric field, and narrow-band noise) are reported for nanoribbon specimens of NbSe _3 with thicknesses as low as 18 nm. As the sample thickness decreases, the resistive anomalies characteristic

Energy band modulation of graphane by hydrogen-vacancy chains: A first-principles study

AIP Advances, 2014
We investigated a variety of configurations of hydrogen-vacancy chains in graphane by first-principles density functional calculation. We found that graphane with two zigzag H-vacancy chains segregated by one or more H chain is generally a nonmagnetic ...
