TL;DR
This paper investigates how quantum interference affects magnetoconductivity in gated 2D quantum wells with composition gradients, demonstrating that the Dresselhaus mechanism explains the observed antilocalization behavior.
Contribution
It provides experimental evidence that the Dresselhaus mechanism accounts for antilocalization in 2D quantum wells with composition gradients.
Findings

Quantum interference affects low-field magnetoconductivity
Composition gradient influences quantum transport properties
Abstract
Low-field magnetoconductivity caused by the quantum interference is studied in the gated 2D quantum well structures with the composition gradient. It is shown that the Dresselhaus mechanism well describes an antilocalization minimum on the conductivity-magnetic field curve.
