A Morse manipulator molecule for the modulation of metallic shockley surface states

In this Letter, we propose the full design and simulation of a very complex molecule-device: the miniaturisation down to a single molecule of a Morse manipulator. Our Morse molecule is able to modulate the electronic standing wave pattern of metallic Shockley surface states. Its design is based on a molecular arm holding a phenyl whose distance to the metal surface is controlled by the tip apex of an STM. The molecular arm is mounted on a four legs molecules maintaining the arm away from the surface. The standing wave patterns, the design and simulation of the performances of the detection device for those waves are calculated using the N-ESQC technique. It is the first time such calculation technique is used to predict the behaviour of a complex molecule interacting with a metal surface and with six metallic electrodes.
