    Abstract: A photodetector includes a first semiconductor layer, an absorption structure, a second semiconductor layer, and a barrier structure. The absorption structure is located on the first semiconductor layer, and having a first conduction band, a first valence band, and a first band gap. The second semiconductor layer is located on the absorption structure, and having a second conduction band, a second valence band, and a second band gap. The barrier structure is located between the absorption structure and the second semiconductor layer, and having a third conduction band, a third valence band, and a third band gap. The third conduction band is greater than the second conduction band or the third valence band is less than the second valence band.
