ABSTRACT:
The disclosed semiconductor luminescent device comprises a semiconductive body including a first semiconductor layer formed of a first semiconductive material and sandwiched between a second and a third semiconductor layer formed of a second semiconductive material having a resistivity higher than that of the first material by two orders of magnitude or more. Each of the first, second and third layers includes an n and a p type region. A first and a second electrode are connected to the p and n type regions of the first layer with low resistances respectively. Light is efficiently emitted from the first layer.
