## Abstract

Seeded silicon carbide (SiC) for devices and panels are disclosed. In one example embodiment, a device includes a housing and a window. Further, the window is attached to the housing. In this example embodiment, the window of the device is fabricated using the seeded SiC having a single crystalline structure.
