Latest Patents
Tanaka holds a patent for a light-emitting semiconductor device featuring a quantum well active layer. This invention describes a light-emitting diode that utilizes a low-resistivity silicon substrate. The device includes a buffer layer, an n-type lower confining layer, an active layer with a multiple quantum well configuration, and a p-type upper confining layer. The active layer consists of cyclic alternations of a barrier sublayer of InGaN, a first complementary sublayer of AlGaInN, a well sublayer of InGaN, and a second complementary sublayer of AlGaInN. The specific proportions of these ingredients are crucial, as the complementary sublayers prevent the evaporation or diffusion of indium from neighboring sublayers.
