Real-Time Ellipsometry for Probing Charge-Transfer Processes at the Nanoscale

摘要: Nanoscale charge transfer is important to both the frontier of fundamental science and applications in molecular electronics, photonic, electronic, optical, imaging, catalysis, sensing devices, photovoltaics, energy savings storage. For many those applications, plasmonic metal nanoparticles are with molecules and/or semiconductors, where act as an electron-bridge. Metal experience either by a hopping mechanism involving transient charging nanoparticle electron storage delocalization among/in nanoparticles. This affects density metal, plasmon resonance, therefore, can be detected spectroscopically. chapter discusses examples exploitation spectroscopic ellipsometry real time research tool that advance description understanding phenomena (i) chemisorption metals on semiconductor surfaces, (ii) growth polar (iii) coupling graphene, (iv) between biomolecules, activating processes.
