TL;DR: Strain engineering of α-formamidinium lead iodide (α-FAPbI 3) is investigated using both experimental techniques and theoretical calculations, and it is demonstrated that a compressive strain effectively changes the crystal structure, reduces the bandgap and increases the hole mobility of α -FAPBI 3.

TL;DR: A solution-based lithography-assisted epitaxial-growth-and-transfer method is used to fabricate single-crystal hybrid perovskites on any surface, with precise control of the thickness, area and chemical composition gradient.

TL;DR: The first chemical epitaxial growth of single crystal CH3 NH3 PbBr3 with controlled locations, morphologies, and orientations, using combined strategies of advanced microfabrication, homoepitaxy, and low temperature solution method is reported.

TL;DR: It is made the first observation that single-digit photon absorption can alter the macroscopic electric and optoelectronic properties of a perovskite thin film.

TL;DR: In this paper, an amorphous silicon low-noise photodio was proposed to produce strong cycling excitation process (CEP) effects with high gain and speed at low noise, despite their extremely low mobility and large number of defects.
