As a result, extensive research and funding have been dedicated in the last years in order to obtain superior LED fabrication techniques and designs which may maximize their optical performances. III-V epitaxial quantum dots (QDs) have been considered to design the active layers of these LEDs as these QDs offer the highest level of optoelectronic efficiency. Among various III-V epitaxial QDs, InSb/InAs QDs emit light at the mid-infrared (MIR) range (3-5 µm) through the tuning of Sb composition and as a result, these QDs can be used to detect various hazardous gases with MIR signatures, among other applications. In this framework, the objective of the present Thesis is to explore the applicability of the migration enhanced epitaxy (MEE) growth technique to fabricate these InSb/...
