Molecular movie shows displaced electrons drive gold nanoparticle oscillations

Result defies established models of nanoparticle behaviour

03-Aug-2023 - Photocatalysis, sensors, solar cells: nanoparticles that are excited by light promise a variety of applications, if the processes behind their behaviour can be controlled. One such process is a type of collective electron motions. These movements lead to energy exchange in the nanoparticle that ...
