Ultrafast Charge Carrier Dynamics of Silver Nanowires [pdf]

Ultrafast charge carrier dynamics studies in several materials have given important insights into the relaxation dynamics of carriers and possible band structure of the material. These studies have led to the effective utilization of these materials in the real world. Nanostructures are ubiquitous in material sciences due to a high degree of control in the structure during fabrication and their vast scope of applications. At the nanoscale, the charge carrier dynamics vary significantly from the bulk matter counterpart; hence it be-comes important to study the ultrafast carrier dynamics of these structures as well. Several studies on metal and semiconductor nanostructures have shown that carrier dynamics are very sensitive to the nanostructure size and shape. This results in a high degree of tunability in the nanostructures for diverse applications. An attempt to study ultrafast carrier dynamics of silver nanowires (AgNW) using pump probe spectroscopy is explained. Numerical simulations of nanoparticle and nanorod pump probe behaviour based on Mie theory and two temperature model were performed. The simulations show that the value of the negative absorption maxima tends to increase when the pump wavelength is decreased and the decay time of the pump probe absorbance signal tends to decrease with pump fluence. Finally, single beam transmitted light microscopy was performed on MoS2 powder sample.
