1. A selection element comprising, in a first portion, a stack of at least two amorphous layers, the thickness of each layer in the stack being greater than 1 nm and smaller than or equal to 20 nm, wherein:
the stack comprises at least one assembly of first layers and one assembly of second layers, the first and second layers being made of different materials;
the first layers are made of an alloy comprising a group-15 element and a group-16 element; and
the second layers consist of one or more, nitrogen-doped, oxygen-doped, or carbon-doped group-14 elements.
