Abstract
A semiconductor substrate is provided in the present disclosure. The semiconductor substrate includes a first semiconductor layer and a second semiconductor layer on the first semiconductor layer. The first semiconductor layer has a first lattice constant (L1) and the second semiconductor layer has a second lattice constant (L2). A ratio of a difference (L2-L1) between the second lattice constant (L2) and the first lattice constant (L1) to the first lattice constant (L1) is greater than 0.036.
