Topologically protected interface phonons in two-dimensional nanomaterials: hexagonal boron nitride and silicon carbide
Jin-Wu Jiang, Bing-Shen Wang, Harold S. Park
We perform both lattice dynamics analysis and molecular dynamics simulations to demonstrate the existence of topologically protected phonon modes in a two-dimensional, monolayer he…
Two-dimensional Square Buckled Rashba Lead Chalcogenides
Paul Z. Hanakata, A. S. Rodin, Alexandra Carvalho +3
We propose the lead sulphide (PbS) monolayer as a 2D semiconductor with a large Rashba-like spin-orbit effect controlled by the out-of-plane buckling. The buckled PbS conduction ba…
Intrinsic Rippling Enhances Static Non-Reciprocity in Graphene Metamaterials
Duc Tam Ho, Harold Park, Sung Youb Kim
In mechanical systems, Maxwell-Betti reciprocity means that the displacement at point B in response to a force at point A is the same as the displacement at point A in response to…
Kirigami Actuators
Marcelo A. Dias, Michael P. McCarron, Daniel Rayneau-Kirkhope +4
Thin elastic sheets bend easily and, if they are patterned with cuts, can deform in sophisticated ways. Here we show that carefully tuning the location and arrangement of cuts with…
Tensile fracture behavior of short carbon nanotube reinforced polymer composites: A coarse-grained model
Behrouz Arash, Harold S. Park, Timon Rabczuk
Short-fiber-reinforced polymer composites are increasingly used in engineering applications and industrial products owing to their unique combination of superior mechanical propert…
Mechanical properties of carbon nanotube reinforced polymer nanocomposites: A coarse-grained model
Behrouz Arash, Harold S. Park, Timon Rabczuk
In this work, a coarse-grained (CG) model of carbon nanotube (CNT) reinforced polymer matrix composites is developed. A distinguishing feature of the CG model is the ability to cap…
