In semiconductors, everything is becoming smaller day by day; quantum dots are the smallest nanomaterials available today. Typical sizes of these quantum dots are in the range of 5 to 30 nm in diameter. Variations in size changes many material properties, such as electrical and nonlinear optical properties, making them very different from bulk semiconductors. The size of the QDs results in new quantum phenomena, which yield some extraordinary properties. Material properties change dramatically because quantum effects arise from the confinement of electrons and holes in the material. Hence, semiconductor quantum dots play an important role in designing new devices …
