ABSTRACT:
A semiconductor emitting device is provided which is capable of emitting a blue light. The device includes a first clad layer, an active layer and a second clad layer, successively formed on a semiconductor substrate. A nitrogen-doped p-type ZnSSe thin film of low-resistivity having a carrier concentration of not less than 1.times.10.sup.16 cm.sup.-3 and a resistivity of not more than 10 .OMEGA.-cm is used as the first clad layer or the second clad layer.
