Abstract
The disclosed improved GaAs majority carrier rectifying barrier diodes comprise a p.sup.+ region between semiconductor regions that comprise n-doped material. Exemplary structures are n.sup.+ -i-p.sup.+ -i-n.sup.+ and n.sup.+ -n-p.sup.+ -n-n.sup.+. The improvement comprises use of carbon as the p-dopant and results in readily manufacturable reliable devices.
