Abstract
A device includes a first doped semiconductor region and a second oppositely doped semiconductor region that are separated by an undoped or lightly-doped semiconductor drift region. The device further includes a first electrode structure making an ohmic contact with the first doped semiconductor region, and a second electrode structure making a universal contact with the second doped semiconductor region. The universal contact of the second electrode structure allows flow of both electrons and holes into, and out of, the device.
