Selector and non-volatile storage device

A selector comprising:

• a first electrode;
• a second electrode;
• and
• a selector layer provided between the first electrode and the second electrode, the selector layer containing SixTeyNz (x+y+z≤100) or SixTeyOwNz (w+x+y+z≤100),
• wherein the x, y, and z of the SixTeyNz satisfy the following:
• 0<x≤35, 15≤y≤50, and 50<z≤85,
• 0<x≤45, 15≤y≤55, and 40<z≤85, or
• 0<x≤55, 15≤y≤65, and 30<z≤85, and
• wherein the w, x, y, z of the SixTeyOwNz satisfy the following:
• 0<x≤35, 15≤y≤50, and 50<w+z≤85,
• 0<x≤45, 15≤y≤55, and 40<w+z≤85, or
• 0<x≤55, 15≤y≤65, and 30<w+z≤85,
• wherein the selector layer contains SixTeyNz, and the SixTeyNz has a Te bond ratio, the Te bond ratio being a ratio of the sum of the number of Te—Te bonds, the number of Te—Si bonds, and the number of Te—N bonds in the SixTeyNz to the sum of the number of Te—Te bonds, the number of Te—Si bonds, the number of Te—N bonds, the number of Si—Si bonds, the number of Si—N bonds, and the number of N—N bonds in the SixTeyNz, wherein the Te bond ratio is 20% or more,
• wherein the Te bond ratio does not exceed 70%.
