Majorana fermion and Weyl fermion have matters and antimatters. But Majorana fermion has zero resistance and Weyl fermion has a resistance. It was confirmed that CP symmetry is preserved in the case of Dirac fermion because it only has spin current as the antimatter. Dirac fermion is supercurrent because CP symmetry is preserved by double schottky contact, but the Majorana fermion with ohmic contact has decreased current due to symmetry violation. Parity symmetry conservation was confirmed from the electrical properties of transistors, and charge symmetry conservation was confirmed in diode properties.
