摘要： A semiconductor structure comprising a matrix having a first cubic Group-III nitride with a first band gap, and a second cubic Group-III nitride having a second band gap and forming a region embedded within the matrix. The second cubic Group-III nitride comprises an alloying material which reduces the second band gap relative to the first band gap, a quantum wire is defined by a portion within the region embedded within the matrix, the portion forming a one-dimensional charge-carrier confinement channel, wherein the quantum wire is operable to exhibit emission luminescence which is optically polarised.
