Strain-engineered electronic and optoelectronic attributes of FAGeCl3 perovskite under biaxial strain and spin-orbit coupling: A DFT framework
The search for stable and lead-free perovskite materials has attracted considerable interest in next-generation optoelectronic and photovoltaic applications. This paper presents a detailed first-principles study of the structure, electronic, optical, and transport properties of formamidinium germanium trichloride (FAGe...
