Colloidal Quantum Dots on a Matrix of Silicon Photomultiplier Microcells
The technology employs colloidal quantum dots (CQDs), in which a CQD layer is arranged over an array of SiPM microcells of an image sensor for an imaging module.

SiC substrates are in demand for high power applications such as electric vehicles, solar panels, and industrial electronics. A physical vapor transport (PVT) apparatus for growth of silicon carbide (SiC) ingots can be improved by incorporating a moveable source. During growth of the ingot, the shape of the growth interface can be maintained as a convex shape by keeping a substantially constant distance between the growth interface and the source material. It is shown that temperature gradients during the growth phase are also influenced by the shape of the growth interface. By moving the source during crystal growth, the resulting SiC ingot can be taller with fewer defects, and can be less likely to crack during subsequent grinding or polishing operations.
