The typical structure of InAs quantum dot (QD) layers on InP substrate is available with wavelength of 1.55um for QD photodetector. Quantum dot is called semiconductor nanocrystals (NCs), which refer to three-dimensional constrained nanomaterials with a radius smaller than or close to the exciton [...]
