“…22,24 The physical parameters of the Cd 0.8 Zn 0.2 Te QWRs summarized in Table I were determined by using electronic parameters from the literatures. [25][26][27][28] The effective masses of the electrons and the heavy holes, the lattice constants, and the other physical parameters of Cd 0.8 Zn 0.2 Te were estimated by using a linear interpolation of Vegard's law. 29…”

Interband transition energies and carrier distributions of the Cd x Zn 1−x Te/ ZnTe quantum wires ͑QWRs͒ were calculated by using a finite-difference method ͑FDM͒ taking into account shape-based strain effects. The shape of the Cd x Zn 1−x Te/ ZnTe QWRs was modeled to be approximately a half-ellipsoidal cylinder on the basis of the atomic force microscopy image. The excitonic peak energies corresponding to the ground electronic subband and the ground heavy-hole band ͑E 1-HH 1 ͒ at several temperatures, as determined from the FDM calculations taking into account strain effects, were in qualitatively reasonable agreement with those corresponding to the ͑E 1-HH 1 ͒ excitonic transition, as determined from the temperature-dependent photoluminescence spectra.

“…The 7 nm CdSe NPL is seen to have a higher maximum gain over the 11 nm NPL in some cases owing to its lower volume, to transform injected carriers to photon emission. A higher differential gain corresponds to a narrower spectral emission width and a greater speed of modulation [124,125]. The differential gain for the corresponding cases of Fig.…”

T hank you, dear reader, I acknowledge you for reading my thesis! It adds value to the many hours spent writing this, and my journey of over four years leading to it.A great many people have had immense contributions directly or indirectly, in the evolution of this thesis to its current form and shaping my doctoral career in general.My deepest gratitude is to my supervisor, Assoc. Prof. Fan Weijun. I have been amazingly fortunate to have a supervisor who believed in me and gave the freedom to explore uncharted waters, but at the same time extended timely guidance to recover whenever my steps faltered. His patience and support has helped me evolve as an independent researcher. My co-supervisor, Prof. Zhang Dao Hua, has been a support figure with invaluable research insights. I am deeply grateful to him for the discussions during meetings, supporting my cause to access reserved characterization tools, and ready financial support.

“…What's more, the differential gain of small quantum dots can maintain a high level for various carrier densities within a certain range. Such feature can be useful as high differential gain should lead to high modulation bandwidth and low frequency chirp as well as narrow line-width capabilities [230,231].…”
