Effect of triangular pits on the mechanical behavior of 2D MoTe: a molecular dynamics study.

Context: Among two-dimensional (2D) materials, transition metal dichalcogenides (TMDs) stand out for their remarkable electronic, optical, and chemical properties. Their atomic thinness also imparts flexibility, making them ideal for flexible and wearable devices. However, our understanding of the mechanical characteristics of molybdenum ditelluride (MoTe), particularly with defects such as pits, remains limited.

Cyclic Wear Reliability of 2D Monolayers.

Understanding wear, a critical factor impacting the reliability of mechanical systems, is vital for nano-, meso-, and macroscale applications. Due to the complex nature of nanoscale wear, the behavior of nanomaterials such as two-dimensional materials under cyclic wear and their surface damage mechanism is yet unexplored. In this study, we used atomic force microscopy coupled with molecular dynamic simulations to statistically examine the cyclic wear behavior of monolayer graphene, MoS, and WSe.

Temperature-dependent failure of atomically thin MoTe.

Context: In this study, we investigated the mechanical responses of molybdenum ditelluride (MoTe) using molecular dynamics (MD) simulations. Our key focus was on the tensile behavior of MoTe with trigonal prismatic phase (2H-MoTe) which was investigated under uniaxial tensile stress for both armchair and zigzag directions. Crack formation and propagation were examined to understand the fracture behavior of such material for varying temperatures.

High-Throughput Continuous Production of Shear-Exfoliated 2D Layered Materials using Compressible Flows.

2D nanomaterials are finding numerous applications in next-generation electronics, consumer goods, energy generation and storage, and healthcare. The rapid rise of utility and applications for 2D nanomaterials necessitates developing means for their mass production. This study details a new compressible flow exfoliation method for producing 2D nanomaterials using a multiphase flow of 2D layered materials suspended in a high-pressure gas undergoing expansion.
