Claim 0:
1. A capacitor comprising:
a first porous semiconductor having a plurality of pores having an average pore size of between 20 nm and 200 nm;
at least one electric conductor; and
at least a portion of the first porous semiconductor being in contact with at least a portion of the at least one electric conductor via a heterocontact with a potential barrier,
wherein the at least one electric conductor infiltrates the plurality of pores of the first porous semiconductor, and materials used to form the first porous semiconductor and/or the at least one electric conductor are selected such that the heterocontact is formed without applying an external voltage, as a result of diffusion of charge carriers, which is more than 0.5 V.
