Observation of Internal Electric Charge in InP Self-Assembled Quantum Dots

Abstract

Heterostructures with lnP self-assembled quantum dots were studied. Strong Franz-Keldysh oscillations were found in their nonlinear reflection spectra. These oscillations manifest the presence of built-in electric field. The field originates from electric charge gathered by dots during the growth process.
