Abstract:
A semiconductor material, comprising:at least one group III-V region doped by an n-type dopant; wherein the n-type dopant includes a first n-type dopant and at least one of a second n-type dopant and an impurity, the first n-type dopant having a covalent radius different in size than a covalent radius of each of the second n-type dopant and the impurity, such that a local stress in the at least one group III-V region caused by the first n-type dopant is compensated by a local stress in the at least one group III-V region caused by the at least one of the second n-type dopant and the impurity, such that a concentration of the first n-type dopant in the at least one group III-V region is enhanced.
