Gallium nitride compound semiconductor element |
| abstract |
In a gallium nitride semiconductor device comprising annactive layer made of an n-type gallium nitride semiconductornthat includes In and is doped with n-type impurity and a p-typencladding layer made of a p-type gallium nitridensemiconductor that includes Al and is doped with p-typenimpurity, n a first cap layer, made of a gallium nitridensemiconductor that includes n-type impurity of lowernconcentration than that of said active layer and p-typenimpurity of lower concentration than that of said p-typencladding layer, and a second cap layer made of a p-typengallium nitride semiconductor that includes Al and is dopednwith p-type impurity are stacked one on another between saidnactive layer and said p-type cladding layer. |
