A reflection on ‘The synthesis, structure and electronic properties of a lead-free hybrid inorganic–organic double perovskite (MA)2KBiCl6 (MA = methylammonium)’

Abstract

Interest in the field of hybrid double perovskite halides has grown rapidly over the last few years, with important developments in 3D, 2D and 1D systems. Their chemical scope has also expanded from an initial focus on materials containing post-transition metals, which are of potential utility for photovoltaic applications, to recent work that covers transition metals and rare earths with very interesting magnetic and optical properties. This reflection article traces the development of this important area from our 2016 communication in Materials Horizons (F. Wei, Z. Deng, S. Sun, F. Xie, G. Kieslich, D. M. Evans, M. A. Carpenter, P. D Bristowe and A. K. Cheetham, Mater. Horiz., 2016, 3, 328–332, https://doi.org/10.1039/C6MH00053C).
