Advanced Functional Materials, EarlyView.Halide diffusion limits the stability of hybrid halide perovskites for optoelectronic applications and thus needs to be quantified. This study presents an effective interdiffusion model to obtain time‐dependent diffusion coefficients for I− and Br− diffusion from in situ X‐ray diffraction data during the formation of a solid solution MAPbIxBr3‐x from ...

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching
Advanced Functional Materials, EarlyView.A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Single‐Step Synthesis of In‐plane 1T'‐2H Heterophase MoTe2 for Low‐Resistance Contacts
Advanced Functional Materials, EarlyView.A single‐step CVD method is developed to synthesize seamless in‐plane 1T'‐2H MoTe2 heterophase junctions with precise phase control and uniform large‐area coverage. The resulting transistors, incorporating 1T' MoTe2 contacts and 2H MoTe2 channels, exhibit ultralow contact resistance, offering a scalable solution to the long‐standing challenge of ...

Steep‐Switching Memory FET for Noise‐Resistant Reservoir Computing System
Advanced Functional Materials, EarlyView.We demonstrate the steep‐switching memory FET with CuInP2S6/h‐BN/α‐In2Se3 heterostructure for application in noise‐resistant reservoir computing systems. The proposed device achieves steep switching characteristics (SSPGM = 19 mV/dec and SSERS = 23 mV/dec) through stabilization between CuInP2S6 and h‐BN.
