    摘要: An epitaxial structure includes a first epitaxial layer, a second epitaxial layer, and an interface treatment layer. The second epitaxial layer is disposed on the first epitaxial layer. The interface treatment layer is located between the first epitaxial layer and the second epitaxial layer and is in contact with the first epitaxial layer and the second epitaxial layer. The first epitaxial layer, the second epitaxial layer, and the interface treatment layer include the same material. An image contrast ratio of a transmission electron microscope (TEM) of the interface treatment layer to the first epitaxial layer and an image contrast ratio of a TEM of the interface treatment layer to the second epitaxial layer are both greater than 1.005. A method for forming an epitaxial structure is also provided.
