Electronic and Optical Sensitivity of Aluminum-Doped Boron Phosphide Monolayers for DNA Base Detection: A First-Principles Study.

ABSTRACT: Genetic testing has become increasingly important for the early diagnosis of diseases, as it can significantly improve treatment success rates and patient survival. A new type of two-dimensional (2D) material, the boron phosphide (BP) monolayer, has recently been recognized as a semiconductor material with excellent electronic properties, high surface reactivity, and environmental friendliness. In this study, density functional theory (DFT) calculations are employed to investigate the adsorption behavior of nucleobases (A = Adenine, T = Thymine, C = Cytosine, G = Guanine) on an aluminum-doped BP monolayer (Al-doped BP). The optical sensitivity, electronic sensitivity, and work function of the material are also analyzed. The results demonstrate that the presence of aluminum enhances the ads
