The electronic structure and optical properties of monolayer h-BN were investigated using
first-principles calculations. Intrinsic monolayer h-BN is a wide-bandgap semiconductor …

The emergence of negative differential friction (NDF) in two-dimensional (2D) layered
materials, which does not obey the classical Da Vinci–Amontons law of friction, has attracted …

Context Two-dimensional materials are a new and promising research field in materials
science. This is mainly attributed to their unique photoelectric and chemical properties. In …

Nanoelectromechanical systems (NEMS) based on layered materials often rely on
mechanical deformation, which involves relative sliding between layers. And the charge …

There are two models to calculate friction properties with the DFT, which are constant load
model (CLM) and constant interface distance model (CDM). Although the CLM is closer to …
