Diffusionenhanced
Diffusionenhanced is an adjective used in materials science, chemistry, and related fields to describe diffusion processes whose effective rate exceeds that of a reference (baseline) diffusion under the same temperature. It denotes transport that is accelerated by factors beyond thermal energy alone, such as microstructural features or external stimuli.
Mechanisms include defect-assisted diffusion (increased vacancy or interstitial concentrations from irradiation, deformation, or irradiation-induced cascades), grain
Measurement and modeling: diffusionenhanced behavior is studied with tracer diffusion experiments, diffusion couples, or surface-sensitive techniques
Applications: diffusionenhanced concepts underpin alloy design, heat treatment, diffusion bonding, semiconductor doping, and battery electrode materials.
Terminology: the exact usage varies; diffusionenhanced is not a universally standardized term. In many contexts authors
