Title:
LIGHT-RECEIVING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/203059
Kind Code:
A1
Abstract:
The present invention is provided with a first semiconductor layer (102) that is composed of a p-type semiconductor and is formed on a substrate (101), and a second semiconductor layer (103) that is composed of an n-type semiconductor and is formed on the substrate (101). The present invention is also provided with a carrier travel layer (104) that is composed of an undoped semiconductor and is formed between the first semiconductor layer (102) and the second semiconductor layer (103), and an n-type light-absorbing layer (105) that is composed of an n-type semiconductor and is formed between the second semiconductor layer (103) and the carrier travel layer (104). The n-type light-absorbing layer (105) is configured to have a lower bandgap energy than do the other layers.
