1 Introduction Heterostructures assembled using single sheets of 2D materials are highly promising due to the novel properties they exhibit and several advantages they offer in comparison to their isolated counterparts.[1-3] Graphene has been widely explored as a building block in such heterostructures. As a one-atom thick material, the properties of graphene are highly sensitive to its environment.

Organic–inorganic halide perovskites (referred to as perovskites hereafter) are a promising next-generation optoelectronic material for light-emitting diodes (LEDs), solar cells, and photodetectors because of their exceptional optoelectronic properties such as a high light absorption coefficient, tunable bandgap, outstanding carrier mobility, and long carrier diffusion length.1–9 However, their inherent structural instability and susceptibility to environmental conditions (light,10–15...

AbstractWe investigate the vibronic dynamics of a modified version of the p-coumaric acid using real-time time-dependent density-functional theory coupled with the Ehrenfest scheme in the adiabatic local density approximation.
