Adhesion, Stiffness and Instability in Atomically Thin MoS2 Bubbles
David Lloyd, Xinghui Liu, Narasimha Boddeti +4
We measured the work of separation of single and few-layer MoS2 membranes from a SiOx substrate using a mechanical blister test, and found a value of 220 +- 35 mJ/m^2. Our measurem…
Band Gap Engineering with Ultralarge Biaxial Strains in Suspended Monolayer MoS2
David Lloyd, Xinghui Liu, Jason W. Christopher +6
We demonstrate the continuous and reversible tuning of the optical band gap of suspended monolayer MoS2 membranes by as much as 500 meV by applying very large biaxial strains. By u…
Molecular Valves for Controlling Gas Phase Transport Made from Discrete Angstrom-Sized Pores in Graphene
Luda Wang, Lee W. Drahushuk, Lauren Cantley +5
An ability to precisely regulate the quantity and location of molecular flux is of value in applications such as nanoscale 3D printing, catalysis, and sensor design. Barrier materi…
Observation of Pull-in Instability in Graphene Membranes under Interfacial Forces
Xinghui Liu, Narasimha G. Boddeti, Mariah R. Szpunar +6
We present a unique experimental configuration that allows us to determine the interfacial forces on nearly parallel plates made from the thinnest possible mechanical structures, s…
Ultrathin Oxide Films by Atomic Layer Deposition on Graphene
Luda Wang, Jonathan J. Travis, Andrew S. Cavanagh +5
In this paper, a method is presented to create and characterize mechanically robust, free standing, ultrathin, oxide films with controlled, nanometer-scale thickness using Atomic L…
