"MgZnO Quantum Well Structures Surface Acoustic Wave Computational Data Set"

"Surface acoustic waves (SAWs) are highly effective in modulating carrier lifetimes in ZnO\/MgZnO quantum wells. As a SAW propagates along the surface of a piezoelectric material, it generates a traveling piezoelectric potential that periodically modulates the semiconductor band structure. This modulation helps separate electrons and holes, which increases radiative lifetime and enhances coherence properties. In ZnO\/MgZnO heterostructures, carrier recombination is influenced by internal fields from spontaneous and piezoelectric polarization, as well as by SAW effects. By adjusting the Mg content, complete electron\u2013hole separation can be achieved, with an optimized Mg concentration of 0.2 in the MgZnO layer. Simulations of SAW modulation further clarify its impact on carrier lifetimes, showing that ZnO\/MgZnO heterostructure devices have promising prospects for future optoelectronic and quantum applications."
