Abstract:
A semiconducting structure that is comprised by a semiconducting device, whose major constituents include group III and group V elements, forming a II-V semiconducting compound, and whose minor constituents include dopant atoms, the semiconducting structure comprising:a plurality of first layers, the first layers comprising a III-V compound and dopant atoms, wherein the dopant atoms are distributed in a substantially uniform manner; and at lease one second layer, the second layer comprising dopant atoms such that the concentration of dopant atoms in the second layer is larger than the concentration of dopant atoms in the first layers, the second layer comprising impurity atoms, and the second layer being located between two first layers; wherein the thickness of the first layers is such that diffusion of dopant atoms from the second layer into the first layer during the growth of an overall semiconducting device is sufficient to produce a substantially uniformly doped first layer.
