Abstract
The mechanical behavior of graphene under various indentation depths, velocities, and temperatures is studied using molecular dynamics analysis. The results show that the load, elastic and plastic energies, and relaxation force increased with increasing indentation depth and velocity. Nanoindentation induced pile ups and corrugations of the graphene. Resistance to deformation decreased at higher temperature. Strong adhesion caused topological defects and vacancies during the unloading process.
Highlights
Graphene has received a lot of attention due to its good mechanical and electromagnetic properties [1,2,3], including a zero electron bandgap, a high electron emission rate, and elastic scattering [4,5,6]
Studies [10,11,12,13] have found that the bandfield effect of a 10-nm-thick graphene sheet is similar to that of a small nanographite particle
Monolayer graphene is considered a suitable material for investigating two-dimensional quantization phenomena, such as temperature-trigger plasma [14], quantization absorption spectrum [15], and the fractional quantum Hall effect [16]
Summary
Graphene has received a lot of attention due to its good mechanical and electromagnetic properties [1,2,3], including a zero electron bandgap, a high electron emission rate, and elastic scattering [4,5,6]. Atomic-scale graphene can be fabricated using micro-mechanical chop crack [7], thermal expansion [8], and extension growth [9] techniques. Studies [10,11,12,13] have found that the bandfield effect of a 10-nm-thick graphene sheet is similar to that of a small (less than 1.2 nm in diameter) nanographite particle. Novoselov and Geim [7] used graphene to fabricate a small crystal tube. Monolayer graphene is considered a suitable material for investigating two-dimensional quantization phenomena, such as temperature-trigger plasma [14], quantization absorption spectrum [15], and the fractional quantum Hall effect [16]. The hexagonal symmetric structure of graphene makes it a candidate material for nano devices
