Sequential vs. coherent tunneling in double barrier diodes investigated by differential absorption spectroscopy

Journal Article

The charge distributions in the quantum wells of several double barrier diodes were measured. It is found that the ratio of the stored charge to the current is not equal to the coherent state lifetime and is basically insensitive to the amount of scattering. It was experimentally demonstrated that phase breaking collisions take place in the present structures by observing the energy distribution of the stored charge in both single and double resonance structures.
