Abstract: Lead telluride (PbTe), an emerging member of the group IV-VI monochalcogenides, exhibits superior properties such as higher density of states, obvious band anisotropy, and high carrier mobility. Moreover, the stronger nonlinear optical response of quantum dots (QDs) makes this type of low-dimensional material highly competitive for broadband pulse laser applications. In this work, high-quality PbTe QDs are fabricated using a liquid phase exfoliation (LPE) method. Utilizing PbTe QDs as what we believe to be a n… Show more
