  • Optoelectronic devices formed over a buffer
    Patent number: 11069825
    Abstract: An optoelectronic device includes an Sb-based metamorphic photodetector grown over a silicon substrate via a buffer layer. The device includes a layered structure. The layered structure can include a silicon substrate, a buffer layer formed over the Si substrate, and an infrared photodetector formed over the buffer layer. In some embodiments, the buffer layer includes a composite buffer layer having sublayers. For example, the composite buffer layer includes a Ge-based sublayer formed over the substrate, a III-As sublayer grown over the Ge-based sublayer, and a III-Sb sublayer formed over the III-As sublayer.
