We report the use of low-energy nitrogen ion beams to form ultra-thin (x to act as tunnel barriers in Nb/Al–AlNx/Nb Josephson junctions. We fabricated reproducible, high-quality devices with independent control of the ion energy and dose, enabling

The speed of Josephson circuits such as those required for rapid single flux quantum logic is limited by the Josephson plasma frequency, /spl omega//sub p/, which (with few exceptions) increases monotonically with increasing critical current density,
