“…However, in order to obtain an appropriate strain, the active region usually has to be designed as multiple layers, which undoubtedly increases the complexity of sample fabrication in controlling the consistent structure and composition of each layer to achieve consistent output characteristics. 20,21 In view of the above considerations, we propose a novel approach and mechanism to overcome band-gap variation with respect to temperature, based on a kind of self-organized nanowire-well-bound quantum structure that has recently been proposed by our group. [22][23][24] This new material structure exhibits many interesting properties that differ from traditional pure quantum-confined structures (well, wires or dots), as observed in our previous work, such as super-gain spectra, high characteristic temperature, and polarization insensitivity.…”
