Be dual implantation into semi-insulating GaAs to form a p-type buried layer under a n-type active layer.
Theoretical and experimental results verify that it is possible to suppress the effect of the n-type implanted profile tail in the region of the semi-insulating substrate interface using the proper p-type buried layer.
