Patent number: 10770239Abstract: A thin film for an optoelectronic device includes a layered 2D perovskite material. The thin film including the layered 2D perovskite material forms a substantially or nearly single-crystalline highly uniform thin film with strongly preferential out-of-plane alignment of the inorganic perovskite layers. This single-crystalline, highly uniform, and highly aligned thin film of the layered 2D perovskite material may thereby facilitate efficient charge transport in an optoelectronic device.Type: GrantFiled: July 3, 2017Date of Patent: September 8, 2020Assignee: TRIAD NATIONAL SECURITY, LLCInventors: Aditya Mohite, Hsinhan Tsai, Wanyi Nie, Mercouri Kanatzidis, Konstantinos Stoumpos

Patent number: 7592535Abstract: A thermoelectric material of the general formula Ag1?XMmM?Q2+m, wherein M is selected from the group consisting of Pb, Sn, Ca, Sr, Ba, divalent transition metals, and combinations thereof; M? is selected from the group consisting of Bi, Sb, and combinations thereof; Q is selected from the group consisting of Se, Te, S, and combinations thereof; 8?m?24; and 0.01?x?0.7. In embodiments of the invention, the compositions exhibit n-type semiconductor properties. In preferred embodiments, x is from 0.1 to 0.3, and m is from 10 to 18. The compositions may be synthesized by adding stoichiometric amounts of starting materials comprising Ag, M, M?, and Q to a reaction vessel, heating the starting materials to a temperature and for a period of time sufficient to melt the materials, and cooling the reaction product at a controlled rate of cooling.Type: GrantFiled: August 25, 2004Date of Patent: September 22, 2009Assignee: Board of Trustees operating Michingan State UniversityInventors: Mercouri Kanatzidis, Kuei-Fang Hsu
