Height variation measurement by 2D and 3D AFM of ACM. (a) 2D AFM of native ACM, (b) 2D AFM of spin coated ACM, (c) 3D AFM of native ACM, (d) 3D AFM of spin coated ACM, (e) line scan to measure the height variations in native ACM, and (f) line scan to measure the height variations in spin coated ACM. Arrows indicate variations in the height of native and spin coated ACM.
