Abstract
A semiconductor imaging element for generating an electrical signal representing the intensity of incident light includes an avalanche photodiode, having sequential p-type, intrinsic, and n-type layers, with a compositional superlattice as the intrinsic layer, for converting incident light to an electric signal, and a switch electrically connected to the photodiode for receiving and reading out the signal. The photodiode and switch are disposed at least partially overlying each other on the same substrate. A two-dimensional array of the imaging element can be used to generate an electrical signal representing a two-dimensional picture of a material object.
