This study delves into the exploration of AZB-germanene composite systems, which are known for their intriguing characteristics, including the emergence of Kondo features and the precise manipulation of electronic spin induced by light exposure. The spin-polarized signature within trans-AZB exerts a significant influence on the band structure near the Fermi level, highlighting the critical role of conformational changes within the AZB component in regulating the magnetoelectronic coupling within the composite system. The research systematically analyzed the intricate interplay of electronic states within these systems with a specific focus on the potential observation of Kondo-like resonance in the trans-AZB-Ge system, resulting in the development of a spin-polarized electronic current within the junction. Theoretical insights suggest that the presence of a Kondo-like effect has the potential to significantly impact the electronic and magnetic properties of the system, making it a promising avenue for precise electronic control within the field of molecular electronics.
