Abstract
A device including a layered heterostructure with an oxygen-containing material, with a carbon layer and an amorphous oxygen diffusion barrier protecting the carbon layer from etching by oxygen. One or more of a metal, a carbide or an oxide may be in contact with the amorphous oxygen diffusion barrier that has the lowest free energy of oxide formation in the device. Various devices are disclosed as are varieties of carbon allotropes. Methods of protecting carbon, such as diamond from the oxygen etching in processes such as device manufacture are also disclosed.
