Abstract
Various embodiments comprise apparatuses and methods including a light sensor. The light sensor includes a first electrode, a second electrode, a third electrode, and a light-absorbing semiconductor in electrical communication with each of the first electrode, the second electrode, and the third electrode. A light-obscuring material to substantially attenuate an incidence of light onto a portion of the light-absorbing semiconductor is disposed between the second electrode and the third electrode. An electrical bias is to be applied between the second electrode, and the first and the third electrodes and a current flowing through the second electrode is related to the light incident on the light sensor. Additional methods and apparatuses are described.
