Investigations on Gel Grown Lead Iodide and Thin Films of Gel Grown Lead Iodide Single Crystals
Observations on Surface Microtopography of gel grown PbI crystals and thin films of gel 2 grown PbI crystals are reported. Initiation of 2 growth layers, interlacing pattern, dendritic growth, symmetry and asymmetry hexagonal arms and natural triangular etch pits were seen. The surface topography, of gel grown PbI crystals and 2 of thin films of gel grown PbI have been related to 2 the growth ...
متن کاملCritical Role of Methylammonium Librational Motion in Methylammonium Lead Iodide (CH3NH3PbI3) Perovskite Photochemistry.
Raman and photoluminescence (PL) spectroscopy are used to investigate dynamic structure-function relationships in methylammonium lead iodide (MAPbI3) perovskite. The intensity of the 150 cm-1 methylammonium (MA) librational Raman mode is found to be correlated with PL intensities in microstructures of MAPbI3. Because of the strong hydrogen bond between hydrogens in MA and iodine in the PbI6 per...
متن کاملSimulation of Ferroelectric Thin Films
The hysteresis properties of ferroelectric thin films open an elegant and promising way to build nonvolatile memory cells. Our basic goal is to set up a tool which is able to reproduce the macroscopic behavior of the devices by calculating current, voltage and charge at the contacts correctly. Our tool, MINIMOS-NT, provides a rigorous approach to describe the static hysteresis properties of fer...
متن کاملPhotocurrent Mapping in Single-Crystal Methylammonium Lead Iodide Perovskite Nanostructures.
We investigate solution-grown single-crystal methylammonium lead iodide (MAPbI3) nanowires and nanoplates with spatially resolved photocurrent mapping. Sensitive perovskite photodetectors with Schottky contacts are fabricated by directly transferring the nanostructures on top of prepatterned gold electrodes. Scanning photocurrent microscopy (SPCM) measurements on these single-crystal nanostruct...
متن کاملStructure and interstitial iodide migration in hybrid perovskite methylammonium lead iodide
Hybrid perovskites form an emerging family of exceptional light harvesting compounds. However, the mechanism underpinning their photovoltaic effect is still far from understood, which is impeded by a lack of clarity on their structures. Here we show that iodide ions in the methylammonium lead iodide migrate via interstitial sites at temperatures above 280 K. This coincides with temperature depe...
