Geometric control of tilt transition dynamics in single-clamped thermalized elastic sheets
Roberto Abril Valenzuela, Paul Z. Hanakata, Mark J. Bowick
We study the finite-temperature dynamics of thin elastic sheets in a single-clamped cantilever configuration. This system is known to exhibit a tilt transition at which the preferr…
Vibrations and tunneling of strained nanoribbons at finite temperature
Paul Z. Hanakata, Sourav S. Bhabesh, David Yllanes +2
Crystalline sheets (e.g., graphene and transition metal dichalcogenides) liberated from a substrate are a paradigm for materials at criticality because flexural phonons can fluctua…
Curvature as an external field in mechanical antiferromagnets
Abigail Plummer, Paul Z. Hanakata, David R. Nelson
A puckered sheet is a freestanding crystalline membrane with an embedded array of bistable buckled units. Recent work has shown that the bistable units behave like spins in a two-d…
Anomalous thermal expansion in Ising-like puckered sheets
Paul Z. Hanakata, Abigail Plummer, David R. Nelson
Motivated by efforts to create thin nanoscale metamaterials and understand atomically thin binary monolayers, we study the finite temperature statistical mechanics of arrays of bis…
Thermal buckling and symmetry breaking in thin ribbons under compression
Paul Z. Hanakata, Sourav S. Bhabesh, Mark J. Bowick +2
Understanding thin sheets, ranging from the macro to the nanoscale, can allow control of mechanical properties such as deformability. Out-of-plane buckling due to in-plane compress…
Forward and Inverse Design of Kirigami via Supervised Autoencoder
Paul Z. Hanakata, Ekin D. Cubuk, David K. Campbell +1
Machine learning (ML) methods have recently been used as forward solvers to predict the mechanical properties of composite materials. Here, we use a supervised-autoencoder (sAE) to…
Accelerated search and design of stretchable graphene kirigami using machine learning
Paul Z. Hanakata, Ekin D. Cubuk, David K. Campbell +1
Making kirigami-inspired cuts into a sheet has been shown to be an effective way of designing stretchable materials with metamorphic properties where the 2D shape can transform int…
Strain-induced gauge and Rashba fields in ferroelectric Rashba lead chalcogenide PbX monolayers (X = S, Se, Te)
Paul Z. Hanakata, A. S. Rodin, Harold S. Park +2
One of the exciting features of two-dimensional (2D) materials is their electronic and optical tunability through strain engineering. Previously, we found a class of 2D ferroelectr…
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…
Spin-Orbit Dirac Fermions in 2D Systems
Aleksandr S. Rodin, Paul Z. Hanakata, Alexandra Carvalho +3
We propose a novel model for including spin-orbit interactions in buckled two dimensional systems. Our results show that in such systems, intrinsic spin-orbit coupling leads to a f…
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…
Highly Stretchable MoS Kirigami
Paul Z. Hanakata, Zenan Qi, David K. Campbell +1
We report the results of classical molecular dynamics simulations focused on studying the mechanical properties of MoS kirigami. Several different kirigami structures were st…
A Unifying Framework to Quantify the Effects of Substrate Interactions, Stiffness, and Roughness on the Dynamics of Thin Supported Polymer Films
Paul Z. Hanakata, Beatriz A. Pazmiño Betancourt, Jack F. Douglas +1
Changes in the dynamics of supported polymer films in comparison to bulk materials involve a complex convolution of effects, such as substrate interactions, roughness and complianc…
