Fig. 5: Yield strength σy as a function of fracture toughness KIc of single and multilayer thin films reported in the literature, see Supplementary Note 8.
From: Al2O3/Al hybrid nanolaminates with superior toughness, strength and ductility
The error bars are extracted directly from the referenced sources. Measurement data on the deposition sputtered single layer Al2O3 film and the Al2O3-Al-Al2O3 laminate film produced in this work are included with star symbols. The dashed lines are contours of equal critical crack length ac, defined in the supplementary Note 8. The dotted line divides the map into two fracture mode regimes; the hatched region highlights a strength-toughness regime for which no representative material system could be identified.
