Abstract: A superlattice cell that includes Group IV elements is repeated multiple times so as to form the superlattice. Each superlattice cell has multiple ordered atomic planes that are parallel to one another. At least two of the atomic planes in the superlattice cell have different chemical compositions. One or more of the atomic planes in the superlattice cell one or more components selected from the group consisting of carbon, tin, and lead. These superlattices make a variety of applications including, but not limited to, transistors, light sensors, and light sources.

Abstract: A light-sensing device includes a pixel array. Multiple pixels in the pixel array each includes pixel electronics. The pixel electronics include low light level electronics in communication with a light sensor and high light level electronics in communication with the same light sensor. The pixel electronics acquire data from the light sensor. During the data acquisition, the pixel electronics can transition between using the high light level electronics to acquire the data and using the low light level electronics to acquire the data.
