TL;DR: An antisolvent vapor-assisted crystallization approach is reported that enables us to create sizable crack-free MAPbX3 single crystals with volumes exceeding 100 cubic millimeters, which enabled a detailed characterization of their optical and charge transport characteristics.

TL;DR: Signatures of the molecular crossover transition are evident in changes in the unoccupied states and the related shift from diamagnetic to paramagnetic characteristics, which may point the way to the molecular magneto-electric effect on devices.

TL;DR: Temperature- and coverage-dependent studies of the Au(1 1‬1)-supported spin crossover Fe(II) complex (SCO) with a suite of surface-sensitive spectroscopy and microscopy tools show that the substrate inhibits thermally induced transitions of the molecular spin state, so that both high-spin and low-spin states are preserved far beyond the spin transition temperature of free molecules.

TL;DR: In this article, the electronic structure and band dispersion of methylammonium lead bromide, CH3NH3PbBr3, have been investigated through a combination of angle-resolved photoemission spectroscopy (ARPES) and inverse photo-emission spectrum analysis (IPES), as well as theoretical modeling based on density functional theory.

TL;DR: The direct observation of the complete electronic band structure of a family of PbS CQD solids via photoelectron spectroscopy is reported, contributing to a marked improvement in the device performance.
