Controlling electron transfer channels in a plasmonic scanning tunneling microscope junction under light excitation

Key Points

• The central aim is to manage electron transfer channels activated by n-photon absorption in a scanning tunneling microscope.
• Demonstrated control of electron transfer channels for n = 0, 1, and 2 under light excitation.
• Utilized a plasmonic scanning tunneling microscope setup.
• Achieved systematic control of electron transfer channels.
• Found that the number of photons (n) plays a crucial role in activating these channels.
