Atomic-Scale Observation of Symmetry Breaking in Altermagnetic MnTe
Guodong Ren, Jonathan M. DeStefano, Xiao-Wei Zhang +20
The recent discovery of altermagnetism has sparked growing interest in compensated magnetic systems as promising platforms for highly scalable spintronics. Altermagnetism is a dist…
Degradation Dynamics of Perovskite Solar Cells Under Fixed Reverse Current Injection
Fangyuan Jiang, Haruka Koizumi, Hannah Contreras +8
Previous studies of reverse-bias stability in perovskite solar cells have focused primarily on voltage controlled reverse-bias tests. Here we instead present an investigation of pe…
Deterministic Printing of Single Quantum Dots
Gregory G. Guymon, Hao A. Nguyen, David Sharp +7
The unique optical properties of quantum dots (QDs), size-tunable emission and high quantum yield, make them ideal candidates for applications in secure quantum communication, quan…
Comparing Machine Learning and Physics-Based Nanoparticle Geometry Determinations Using Far-Field Spectral Properties
Mengqi Sun, Zixu Huang, Muammer Y. Yaman +3
Anisotropic metal nanostructures exhibit polarization-dependent light scattering. This property has been widely exploited to determine geometries of subwavelength structures using…
Surface Passivation for Halide Optoelectronics: Comparing Optimization and Reactivity of Amino-Silanes with Formamidinium
Zixu Huang, Farhad Akrami, Junxiang Zhang +3
Amino-silane-based surface passivation schemes are gaining attention in halide perovskite optoelectronics, with varying levels of success. We compare surface treatments using (3-am…
Deposition-Dependent Coverage and Performance of Phosphonic Acid Interface Modifiers in Halide Perovskite Optoelectronics
Hannah Contreras, Aidan O'Brien, Margherita Taddei +10
In this work, we study the effect of various deposition methods for phosphonic acid interface modifiers commonly pursued as self-assembled monolayers in high-performance metal hali…
