Talbot effect in InAs/GaAs coupled cylindrical quantum dots ensemble

Theoretical Investigation and Improvement of Characteristics of InAs/GaAs Quantum Dot Intermediate Band Solar Cells by Optimizing Quantum Dot Dimensions

“…Dimensions of cylindrical QDs in this structure are shown in Figure 2. The self-assembly growth method typically results in pyramid-shaped QDs [44]; but in practical endeavors, efforts have been made to find ways to implement it, although various growth methods have been employed to achieve this goal. One method to achieve cylindrical QDs involves the use of patterned substrates or templates.…”

“…By creating specific patterns on the substrate surface, such as nanoholes or nanowires, researchers can guide the growth of the quantum dots into cylindrical shapes. Additionally, molecular beam epitaxy (MBE) and metalorganic chemical vapor deposition (MOCVD) techniques allow for precise control over the growth parameters, such as temperature, pressure, and flux rates, which can influence the shape and size of the quantum dots [44].…”

Talbot effect in anti-PT symmetric synthetic photonic lattices

“…The Talbot distance Z T is defined as the position at which waves periodically reproduce themselves along the propagation direction [4] . In addition to optics, this effect has also been widely studied and applied in condensed matter [5,6] , quantum revivals [7,8] , X-ray [9,10] , plasmonic [11,12] , electron [13,14] , primenumber decomposition [15] , and so on. Currently, research on the optical Talbot effect has expanded from the spatial domain [16][17][18] to the temporal domain [19][20][21] , from linear to nonlinear [22] , and from continuous media to discrete systems [16][17][18]23] .…”
