On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions
Advanced Materials, EarlyView.We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices
Advanced Materials Technologies, EarlyView.Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...
