Why is Controlling Impurity Concentration Important?
The presence of impurities can alter the physical and chemical properties of nanomaterials. For instance, in semiconductors, impurities can affect the bandgap, carrier concentration, and mobility. In catalysis, impurities can poison active sites, reducing the efficiency of the catalyst. Therefore, precise control over impurity concentration is essential for the fabrication of high-performance nanodevices and materials.
