Abstract: Disclosed is an optical sensor including a three-dimensional (3D) material layer doped with first conductivity type impurities at a first doping concentration, and a two-dimensional material layer doped with second conductivity type impurities at a second doping concentration and arranged in contact with the three-dimensional material layer to form a type II band alignment with the three-dimensional material layer.
