Claim 11:
12. A sample for physical analysis, comprising: a sample to be inspected and a contrast enhancement layer, wherein the contrast enhancement layer is formed on a surface of the sample to be inspected, and includes m layers of first material layers and n layers of second material layers that are stacked upon one another, m and n each being zero or a positive integer, and satisfying the following relationship: (m+n)>0; and
wherein a material of each of the first material layers is different from a material of each of the second material layers, and each one of the first and second material layers has a thickness that does not exceed 0.1 nm; wherein in an image captured by an electron microscope, a difference between an average grayscale value of a surface layer image of the sample to be inspected and an average grayscale value of an image of the contrast enhancement layer is at least 50.
