Groundbreaking study reveals small polaron effect in Dion-Jacobson 2D lead halide perovskites, enhancing spin lifetime and optoelectronic performance

The study discovered a giant deformation potential of 123 eV, leading to exceptionally long polarization response times and enhanced spin lifetimes. Small polaron formation was confirmed through various techniques, including optical Kerr spectroscopy, X-ray diffraction, and phonon dynamics.
