As electronics move forward and researchers are constantly trying to figure out what the next step in tech will be, there is one field of work that is getting a lot of attention from a small group of people. What they are looking at is refining the potential of perovskite crystals, where a perovskite crystal is any crystalline structure that mimics that off calcium titanium oxide (CaTiO3).
With a hole still to be filled for the next major materials in the progression of semiconductors a group of Department of Energy scientists have found a means of creating square 2-Dimensional perovskite sheets. Though the chemical composition of the material that they used is quite daunting – CH3NH3PbI3 – it holds much more promise in terms of procedural integration than other methods of producing 2-D perovskites. Traditional methods such as chemical vapor deposition and exfoliation can only create thick plates of perovskite which cannot be used in the thin-film manner intended for 2-D sheets. By simply growing the free-standing 2-D sheets the scientists were able to tap into a few different factors that can be tuned to create varying material properties.
As perovskites enter the scene, other potentials such as graphene seem to have taken a back seat. Of course there is still lots of work to be done with the potentials, but for now it would seem as though organic-inorganic hybrid perovskites have taken the stage.
