T2.1 Colloidal Crystals Engineered from Anisotropic Nanoparticles and DNA Haixin Lin (Northwestern University) DNA-mediated programmable assembly is a promising route for synthesizing novel materials. This strategy has been successfully used to synthesize crystalline structures with more than 35 different symmetries and over 500 structures. However, most of the properties of these colloidal crystals are dictated …

T1.6 2D Dion-Jacobson Hybrid Lead Iodide Perovskites with Aromatic Diammonium Cations Xiaotong Li (Northwestern University), Weijun Ke (Northwestern University), Mercouri Kanatzidis (Northwestern University) Two-dimensional (2D) halide perovskites have extraordinary optoelectronic properties and structural turnabilities. Among them, the Dion-Jacobson (DJ) phases incorporating diammonium cations with the inorganic layers stacking exactly on top of each other are …

T1.5 Uniaxial Expansion of the 2D Ruddlesden-Popper Perovskite Family for Improved Environmental Stability Ioannis Spanopoulos (Northwestern University), Mercouri Kanatzidis (Northwestern University), Ido Hadar (Northwestern University), Weijun Ke (Northwestern University), Qing Tu (Northwestern University), Vinayak Dravid (Northwestern University) The unique hybrid nature of 2D Ruddlesden-Popper (R-P) perovskites has bestowed upon them not only tunability of their …

T1.4 Ultrathin Metasurfaces for the Visible Light Based on Dielectric Resonators Haogang Cai (Argonne National Laboratory) Metasurface-based optical elements enable abrupt wavefront engineering by locally controlling the properties (amplitude, phase, etc.) of the incident illumination. They hold great potential to promote a new generation of wearable devices and thin optical systems for imaging and sensing. …

T1.3 MOCVD Growth of All III-phosphide (AlInP-InGaP) Distributed Bragg Reflectors for Use in Multijunction Solar Cells* David Rowell (Microlink Devices), Kamran Forghani (Microlink Devices), Rao Tatavarti (Microlink Devices) We report on the MOCVD growth of all III-phosphide (AlInP-InGaP) Distributed Bragg Reflectors and their applications for multijunction (MJ) solar cell devices. DBR’s with peak reflectance of 0.89um …

T1.2 Light-spin Interaction in Optomagnonic Whispering Gallery Resonators Xufeng Zhang (Argonne National Laboratory) Photonics provides high-precision methods for detecting and manipulating electronic signals. On the other hand, magneto-optical interactions make it possible to control magnetism using optical photons. In particular, collective magnetic excitation, which are also known as spin waves or magnons, can be coherently …

T1.1 High-speed Room-temperature Control of Quantum Emitters with Plasmonic Nanostructures Simeon I. Bogdanov (Purdue University) Quantum technologies simultaneously require accurate control over elementary quantum systems and robust protection from interactions with their environment. Single photons are arguably the best candidates for realizing quantum networks thanks to their fast propagation speed and low decoherence rates. However, …
