Abstract
An image sensor including a semiconductor layer. A light absorber layer couples with the semiconductor layer at a pixel of the image sensor and absorbs incident light to substantially prevent the incident light from entering the semiconductor layer. The light absorber layer heats a depletion region of the semiconductor layer in response to absorbing the incident light, creating electron/hole pairs. The light absorber layer may include one or more narrow bandgap materials.
