Abstract (en)

[origin: WO2020201547A1] The capacitor comprises: a first porous semiconductor with an average pore size ranging between 20 nm and 200 nm, preferably between 40 nm and 100 nm, and at least one second electric conductor, wherein the second electric conductor infiltrates the porous structure, and the involved materials are selected such that a potential barrier is formed between the first porous semiconductor and the second conductor without applying an external voltage as a result of the diffusion of load carriers, said voltage equaling preferably more than 0.5 V, particularly more than 0.7 V, particularly more than 1 V, particularly more than 1.4 V. A dielectric layer with a thickness of 1 nm to 10 nm is arranged preferably between the first porous semiconductor and the second electric conductor.
