1. A carbon-based clathrate compound comprising:
(i) a clathrate lattice with atoms of at least one element selected from the group consisting of carbon and boron as a host cage structure;
(ii) guest atoms encapsulated within the cages of the clathrate lattice; and
(iii) substitution atoms that are substituted for at least one portion of the carbon and boron atoms that constitute the clathrate lattice, wherein:
the guest atoms are Sr.
