Limitation of Fermi level shifts by polaron defect states in hematite photoelectrodes

Hematite has been proposed as a suitable photocatalyst for water splitting based on its stability and appealing optical band gap, but its performance has not reached theoretical expectations. Here the authors show that this is due to intra-gap polaronic states that reduce the effective electronic ba...
