# §231.118. Semiconductors critical to national security.


Semiconductors critical to national security means:

- (a) Semiconductors utilizing nanomaterials, including 1D and 2D carbon allotropes such as graphene and carbon nanotubes;
- (b) Compound and wide- and ultra-wide bandgap semiconductors;
- (c) Radiation-hardened by process (RHBP) semiconductors;
- (d) Fully depleted silicon on insulator (FD-SOI) semiconductors, other than with regard to semiconductor packaging operations with respect to such semiconductors of a 28-nonometerer generation or older;
- (e) Silicon photonic semiconductors;
- (f) Semiconductors designed for quantum information systems;
- (g) Semiconductors designed for operation in cryogenic environments (at or below 77 Kelvin); and
- (h) Any other semiconductors that the Secretary, in consultation with the Secretary of Defense and the Director of National Intelligence, determines is critical to national security and issues a public notice of that determination.
