Surface Tension Effects on Surface Instabilities of Dielectric Elastomers
Saman Seifi, Qiming Wang, Harold S. Park
Dielectric elastomers have recently been proposed for various biologically-relevant applications, in which they may operate in fluidic environments where surface tension effects ma…
A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond
Deji Akinwande, Christopher J. Brennan, J. Scott Bunch +17
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitrid…
Auxetic Nanomaterials: Recent Progress and Future Development
Jin-Wu Jiang, Sung Youb Kim, Harold S. Park
Auxetic materials (materials with negative Poisson's ratio) and nanomaterials have independently been for many years two of the most active research fields in material science. Rec…
Intrinsic Negative Poisson's Ratio for Single-Layer Graphene
Jin-Wu Jiang, Tienchong Chang, Xingming Guo +1
Negative Poisson's ratio (NPR) materials have drawn significant interest because the enhanced toughness, shear resistance and vibration absorption that typically are seen in auxeti…
Graphene kirigami as a platform for stretchable and tunable quantum dot arrays
D. A. Bahamon, Zenan Qi, Harold. S. Park +2
The quantum transport properties of a graphene kirigami similar to those studied in recent experiments are calculated in the regime of elastic, reversible deformations. Our results…
Polarization and valley switching in monolayer group-IV monochalcogenides
Paul Z. Hanakata, Alexandra Carvalho, David K. Campbell +1
Group-IV monochalcogenides are a family of two-dimensional puckered materials with an orthorhombic structure that is comprised of polar layers. In this article, we use first princi…
