Adhesion of 2D MoS to Graphite and Metal Substrates Measured by a Blister Test
Metehan Calis, David Lloyd, Narasimha Boddeti +1
Using a blister test, we measured the work of separation between MoS membranes from metal, semiconductor, and graphite substrates. We found a work of separation ranging from 0.…
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…
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…
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…
