Buckle Delamination Of Textured Tio Thin Films On Mica

Stress Induced Delamination Methods For The Study Of

the compressive stresses in thin film would cause interface delamination or buckle over the substrate 123456. these failures mainly depend on the mechanical properties of films and.on the growth of buckledelamination pattern in compressed,the buckle delamination occurred when the compressive stress overcome the adhesion strength of the tio2 films on mica. a value of adhesion strength around 0.9 mpa for tio2 on mica is obtained. the
