Grafted Low‐Leakage Si/AlN p‐n Diodes Enabled by Fluorinated AlN Interface

open access: yesAdvanced Materials Interfaces, EarlyView.
This work demonstrates a fluorination‐based interface engineering strategy that transforms oxygen‐terminated AlN surfaces into fluorine‐terminated interfaces for grafted p‐Si/n‐AlN diodes. By combining pseudo‐ALE oxide removal, XeF2 fluorination, and ultrathin SiNx stabilization, the engineered interface suppresses defect‐assisted reverse leakage by ...

Low‐Temperature Gold Deposition Improves CdTe Back Contacts

open access: yesAdvanced Materials Interfaces, EarlyView.
Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

open access: yesAdvanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

open access: yesAdvanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.
