Raman Active Modes of Black Phosphorene

In this article, we introduce a force constant model that has been crafted for Black phosphorene. The purpose of this model is to replicate the vibrational properties obtained through density functional theory calculations (DFT). A thorough comparison is conducted between the outcomes of this model and the experimental data derived from Raman spectroscopy measurements. The comparison reveals a remarkable concurrence between the computational predictions and the actual Raman experimental results. We have achieved a strong alignment with the principles of group theory when determining the quantity of Raman-active modes in black phosphorene.
