Exponent equality for capture-zone scaling in island nucleation: Theory and application to organic films
Alberto Pimpinelli, Levent Tumbek, Adolf Winkler
It is known in thin-film deposition that the density of nucleated clusters varies with the deposition rate as a power law, . The exponent is a function of t…
Feasibility of Lithium Storage on Graphene and Its Derivatives
Yuanyue Liu, Vasilii I. Artyukhov, Mingjie Liu +2
Nanomaterials are anticipated to be promising storage media, owing to their high surface-to-mass ratio. The high hydrogen capacity achieved by using graphene has reinforced this op…
The role of screened exact exchange in accurately describing properties of transition metal oxides: Modeling defects in LaAlO3
Fedwa El-Mellouhi, Edward N. Brothers, Melissa J. Lucero +1
The properties of many intrinsic defects in the wide band gap semiconductor LaAlO3 are studied using the screened hybrid functional of Heyd, Scuseria, and Ernzerhof (HSE). As in pr…
Constructing Metallic Nanoroad on MoS2 Monolayer via Hydrogenation
Yongqing Cai, Zhaoqiang Bai, Hui Pan +3
Monolayer transition metal dichalcogenides recently emerge as a new family of two-dimensional material potentially suitable for numerous applications in electronic and optoelectron…
Giant Quasiparticle Bandgap Modulation in Graphene Nanoribbons Supported on Weakly Interacting Surfaces
Xueping Jiang, Neerav Kharche, Paul Kohl +5
In general, there are two major factors affecting bandgaps in nanostructures: (i) the enhanced electron-electron interactions due to confinement and (ii) the modified self-energy o…
Intrinsic Magnetism of Grain Boundaries in Two-dimensional Metal Dichalcogenides
Zhuhua Zhang, Xiaolong Zou, Vincent H. Crespi +1
Grain boundaries (GBs) are structural imperfections that typically degrade the performance of materials. Here we show that dislocations and GBs in two-dimensional (2D) metal dichal…
Carbyne from first principles: Chain of C atoms, a nanorod or a nanorope?
Mingjie Liu, Vasilii I. Artyukhov, Hoonkyung Lee +2
We report an extensive study of the properties of carbyne using first-principles calculations. We investigate carbyne's mechanical response to tension, bending, and torsion deforma…
Blue shifting of the A exciton peak in folded monolayer 1H-MoS2
Frank J. Crowne, Matin Amani, A. Glen Birdwell +7
The large family of layered transition-metal dichalcogenides is widely believed to constitute a second family of two-dimensional (2D) semiconducting materials that can be used to c…
Low-frequency surface plasmon excitations in multicoaxial negative-index metamaterial cables
M. S. Kushwaha, B. Djafari-Rouhani
By using an elegant response function theory, which does not require matching of the messy boundary conditions, we investigate the surface plasmon excitations in the multicoaxial c…
Theory of confined plasmonic waves in coaxial cylindrical cables fabricated of metamaterials
M. S. Kushwaha, B. Djafari-Rouhani
We report on the theoretical investigation of the plasmonic wave propagation in the coaxial cylindrical cables fabricated of both right-handed medium (RHM) [with , ] and…
Surface plasmons in coaxial metamaterial cables
Manvir S. Kushwaha, Bahram Djafari-Rouhani
Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials -- engineered composites -- can be designed to have properties difficult or impossible t…
Review of Anisotropic Terahertz Material Response
T. Arikawa, Q. Zhang, L. Ren +2
Anisotropy is ubiquitous in solids and enhanced in low-dimensional materials. In response to an electromagnetic wave, anisotropic absorptive and refractive properties result in dic…
Neutral defects in SrTiO3 studied with screened hybrid density functional theory
Fedwa El-Mellouhi, Edward N Brothers, Melissa J Lucero +1
The properties of neutral defects in SrTiO3 are calculated using the screened hybrid density functional of Heyd, Scuseria, and Ernzerhof. The formation energies, the crystal field…
Density Functionals that Recognize Covalent, Metallic, and Weak Bonds
Jianwei Sun, Bing Xiao, Yuan Fang +6
Computationally-efficient semilocal approximations of density functional theory at the level of the local spin density approximation (LSDA) or generalized gradient approximation (G…
Mechanically induced metal-insulator transition in carbyne
Vasilii I. Artyukhov, Mingjie Liu, Boris I. Yakobson
First-principles calculations for carbyne under strain predict that the Peierls transition from symmetric cumulene to broken-symmetry polyyne structure is enhanced as the material…
Second harmonic microscopy of monolayer MoS2
Nardeep Kumar, Sina Najmaei, Qiannan Cui +4
We show that the lack of inversion symmetry in monolayer MoS2 allows strong optical second harmonic generation. Second harmonic of an 810-nm pulse is generated in a mechanically ex…
