    • A diamond heterojunction diode having an improved rectifying characteristics with a small reverse current and a large forward current. Three layers are formed on a low-resistance p-type silicon substrate by the microwave plasma CVD in the order of a B-doped p type semiconducting diamond layer, an insulating undoped diamond layer (thinner than 1 .mu.m), and an n-type semiconducting silicon layer. Ohmic electrodes are formed on the front side of a n-type semiconducting silicon layer and the back side of a substrate. Under a forward bias, the electric field is applied to the intermediate insulating layer to accelerate the transport of holes and electrons. Under a reversed bias, the energy band has a notch as well as a potential barrier due to the intermediate layer thus preventing holes from transporting from the n-type semiconducting diamond layer to the p-type semiconducting diamond layer, resulting in the improved rectifying characteristics.
