Magnetic Precursor to the Structural Phase Transition in V2O3

Advanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

Correlation of Band Bending and Ionic Losses in 1.68 eV Wide Band Gap Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Piperazinium salt treatments with different anions (chloride, iodide, tosylate, and bistriflimide) influence the energetics, carrier dynamics and long‐term stability of 1.68 eV perovskite solar cells. Chloride treatments achieve the highest efficiency (21.5%) but suffer from fast degradation due to ionic losses.

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

CurFi: An automated tool to find the best regression analysis model using curve fitting

Engineering Reports, Volume 4, Issue 12, December 2022., 2022
An automated curve fitting system named “CurFi” is developed that uses linear regression models to fit a curve to a dataset and to find out the best fit model. The system facilitates to upload a dataset, split the dataset into training set and test set, select relevant features and label from the dataset; and the system will return the best fit linear ...

Elucidating the Role of Electric Fields in Fe Oxidation via an Environmental Atom Probe

Angewandte Chemie, EarlyView.
Field‐Assisted Fe Oxidation imaged by Environmental Atom Probe. The oxidation of iron (Fe) at the tip of a sharp needle under high electrostatic fields has been visualized using an Environmental Atom Probe (EAP) and corroborated through Density Functional Theory (DFT) calculations and a mean‐field model applied to a multi‐faceted catalytic grain ...
