Abstract: Here we report a new layered homologous series (Bi2O2Cu2−δSe2)mδ+(Bi2O2Se1−(m/n)δX (m/n)δ)nδ− (X = Cl, Br), composed of the known structural blocks BiOCuSe and Bi2O2Se. These structures are accessed by combining charge-compensating Cu vacancies and (Cl, Br) for Se substitution, in different layers. These new stacking homologoues have properties markedly different from those of the parent materials, and changing the layer stacking affects the properties including the band gap and thermal conductivity.
