Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Temperature‐Dependent Properties of Amino‐As Based InAs/ZnSe Core‐Shell Quantum Dot Films

open access: yesAdvanced Optical Materials, EarlyView.
InAs colloidal quantum dots (CQDs) exhibit tunable optical bandgap covering the near‐infrared spectrum, making them attractive for various optoelectronicapplications. This work demonstrates that their optical properties are partially maintained up to 250°C, where Atomic Force Microscopy (AFM) and Kelvin Probe Force Microscopy (KPFM) measurements reveal
