Absence of Quantized Energy-States Local Diffusion in Semiconductor Quantum-Dash Structures

Not Accessible

Your library or personal account may give you access

Abstract

We present an analysis of InAs/InAlGaAs/InP quantum-dash structures utilizing different degrees of postgrowth-lattice-disordering. The observation of digital transitions among quantized states discards the origins of multiple excited states from a single group of dash ensembles.
