| 摘要 |
A light-emitting diode (LED) constructed of AlGaInP compounds includes a multi-layer window having, in the order of formation, a lightly doped first layer formed of p doped GaP; a low impedance second layer formed of p GaAs; an amorphous conducting layer formed of Indium Tin Oxide (ITO), and a titanium/gold contact. In one embodiment, the contact forms ohmic connections with the second and third layers; and a Schottky diode connection with the first layer. In a second embodiment, the contact forms an ohmic connection with the third layer; and is insulated from direct contact with the first layer.
