Charge localization and trapping at surfaces in lead-iodide perovskites: the role of polarons and defects
Francesco Ambrosio, Daniele Meggiolaro, Edoardo Mosconi, Filippo De Angelis
Abstract
Separate localization of charge carriers for pristine and flat surfaces. Bulk-like physics of defects for the MAI surface while lower formation energies and deeper energy levels for the PbI<sub>2</sub> surface.
