Title:
Dynamical nonlinearity in strained InGaAs (311)A sidewall quantum wires 
Abstract:
Significant optical nonlinearity has been found in InGaAs (311)A sidewall quantum wires by means of time resolvedphotoluminescencemeasurements. A strong reverse quantum confined Stark effect has been observed and attributed to the dynamical screening of both the internal piezoelectric field and the Coulomb interaction between carriers. The time evolution of the quantum wire emission has been reproduced by means of self-consistent calculations that take into account excitonic effects, strain, and...    »
