Ferroelastic Hysteresis in Thin Films of Methylammonium Lead Iodide

Autor: Ryan A. DeCrescent, Kunal Mukherjee, Clayton J. Dahlman, Ram Seshadri, Jon A. Schuller, Rhys M. Kennard, Michael L. Chabinyc

Publikováno v: Chemistry of Materials, vol 33, iss 1

Mechanical strain can modify the structural and electronic properties of methylammonium lead iodide MAPbI3. The consequences of ferroelastic hysteresis, which involves the retention of structural memory upon cycles of deformation, in polycrystalline

Influence of Crystalline and Shape Anisotropy on Electrochromic Modulation in Doped Semiconductor Nanocrystals

Autor: Delia J. Milliron, Shin Hum Cho, Sungyeon Heo, Clayton J. Dahlman, Ankit Agrawal

Publikováno v: ACS Energy Letters. 5:2662-2670

Localized surface plasmon resonance (LSPR) modulation appearing in the near-infrared range in doped semiconductor nanocrystals enriches electrochromic performance. Although crystalline and shape anisotropies influence LSPR spectra, study of their imp

Enhanced Coloration Efficiency of Electrochromic Tungsten Oxide Nanorods by Site Selective Occupation of Sodium Ions

Autor: Taizhi Jiang, Brian A. Korgel, Andrei Dolocan, Clayton J. Dahlman, Corey M. Staller, Delia J. Milliron, Sungyeon Heo

Publikováno v: Nano Letters. 20:2072-2079

Coloration efficiency is an important figure of merit in electrochromic windows. Though it is thought to be an intrinsic material property, we tune optical modulation by effective utilization of ion intercalation sites. Specifically, we enhance the c

Controlling Solvate Intermediate Growth for Phase-Pure Organic Lead Iodide Ruddlesden–Popper (C4H9NH3)2(CH3NH3)n−1PbnI3n+1 Perovskite Thin Films

Autor: Guang Wu, Ryan A. DeCrescent, Rhys M. Kennard, Clayton J. Dahlman, Michael L. Chabinyc, Naveen R. Venkatesan, Michael A. Everest, Jon A. Schuller

Publikováno v: Chemistry of Materials. 31:5832-5844

The growth of Ruddlesden–Popper perovskite thin films of organic lead halides is complicated by the existence of multiple crystallization pathways available to precursors in solution. During thin-f...

Phase Stability and Diffusion in Lateral Heterostructures of Methyl Ammonium Lead Halide Perovskites

Autor: Michael L. Chabinyc, Rhys M. Kennard, Kunal Mukherjee, Hidenori Nakayama, Ram Seshadri, Jon A. Schuller, Clayton J. Dahlman, Ryan A. DeCrescent

Publikováno v: ACS Applied Materials & Interfaces, vol 11, iss 28

Mixed halide hybrid organic-inorganic perovskites have band gaps that span the visible spectrum making them candidates for optoelectronic devices. Transport of the halide atoms in methyl ammonium lead iodide (MAPbI3) and its alloys with bromine has b
