Mechanical properties of monolayer GaS and GaSe crystals
(American Physical Society, 2016-12)
The mechanical properties of monolayer GaS and GaSe crystals are investigated in terms of their elastic constants: in-plane stiffness (C), Poisson ratio (ν), and ultimate strength (σU) by means of first-principles calculations. ...
Quantum-Transport Characteristics of a p–n Junction on Single-Layer TiS3
(Wiley, 2016-12)
By using density functional theory and non-equilibrium Green′s function-based methods, we investigated the electronic and transport properties of a TiS3 monolayer p–n junction. We constructed a lateral p–n junction on a ...
Solution processable neutral state colourless electrochromic devices: Effect of the layer thickness on the electrochromic performance
(Royal Society of Chemistry, 2016)
In this study, a neutral state colourless electrochromic device fabricated through a solution process is introduced. The device contains indium doped transparent oxide coated glass as the transparent conductive electrode, ...
Strong dichroic emission in the pseudo one dimensional material ZrS3
(Royal Society of Chemistry, 2016-09-28)
Zirconium trisulphide (ZrS3), a member of the layered transition metal trichalcogenides (TMTCs) family, has been studied by angle-resolved photoluminescence spectroscopy (ARPLS). The synthesized ZrS3 layers possess a pseudo ...
Unusual lattice vibration characteristics in whiskers of the pseudo-one-dimensional titanium trisulfide TiS3
(Nature Publishing Group, 2016-09-22)
Transition metal trichalcogenides form a class of layered materials with strong in-plane anisotropy. For example, titanium trisulfide (TiS3) whiskers are made out of weakly interacting TiS3 layers, where each layer is made ...
Mg(OH)2-WS2 van der Waals heterobilayer: Electric field tunable band-gap crossover
(American Physical Society, 2016)
Magnesium hydroxide [Mg(OH)2] has a layered brucitelike structure in its bulk form and was recently isolated as a new member of two-dimensional monolayer materials. We investigated the electronic and optical properties of ...
Single layer PbI2: Hydrogenation-driven reconstructions
(Royal Society of Chemistry, 2016)
By performing density functional theory-based calculations, we investigate how a hydrogen atom interacts with the surfaces of monolayer PbI2 and how one- and two-side hydrogenation modifies its structural, electronic, and ...
Structural changes in a Schiff base molecular assembly initiated by scanning tunneling microscopy tip
(IOP Publishing, 2016-07)
We report the controlled self-organization and switching of newly designed Schiff base (E)-4-((4-(phenylethynyl) benzylidene) amino) benzenethiol (EPBB) molecules on a Au (111) surface at room temperature. Scanning tunneling ...
h-AlN-Mg(OH)2 van derWaals bilayer heterostructure: Tuning the excitonic characteristics
(American Physical Society, 2017-02)
Motivated by recent studies that reported the successful synthesis of monolayer Mg(OH)2 [Suslu, Sci. Rep. 6, 20525 (2016)2045-232210.1038/srep20525] and hexagonal (h-)AlN [Tsipas, Appl. Phys. Lett. 103, 251605 (2013)APPL ...
2D vibrational properties of epitaxial silicene on Ag(111)
(IOP Publishing, 2017-03)
The two-dimensional silicon allotrope, silicene, could spur the development of new and original concepts in Si-based nanotechnology. Up to now silicene can only be epitaxially synthesized on a supporting substrate such as ...
