of diffusive conduction and giant ambipolar diffusion," J. Appl.

high speed diffusion mechanisms in semiconductor heterostructures,
diffusive conduction and giant ambipolar diffusion, are compared and
shown to be equivalent descriptions of the same physical process.
Fundamental limits of this process are discussed.
