This device is considerably different from conventional superconductors, and is based on the idea that the voltage that produces Joule heating can be in proportion to the voltage derived from the line integral of an internal electric field employing a condenser when the current is supplied to a doped semiconductor by a current source. In this case, the charge-carrier concentration is spatially nonuniform. The concentration gradient of the current source leads to diffusion of the charge carriers, and the motion of these carriers contributes to the current density. An electric field is not needed to move the charge carriers, because they move by diffusion and not by drift. Because the voltage associated with Joule heating is proportional to the voltage of the internal electric field, the total voltage in the semiconductor is zero; however, the current carried from the current source prevents the total current from being zero. We show that this property of the device results in a superconducting state arising from the diffusion-current state. In our theoretical analysis, we demonstrate that two electrons in the device form a pair and that Bose-Einstein condensation of all pairs is produced. From this result, we derive the existence of a superconducting current without voltage. Furthermore, we have developed an experimental setup and confirmed zero electric resistance and energy emission from the semiconductor. Therefore, we conclude that a new type of superconductivity had been achieved. This phenomenon was observed multiple times and thus can be reproduced.
