Our findings provide new insights into high-resolution probe microscopy imaging with terminated tips, decoupling atoms and molecules by NaCl islands or tip-induced lateral manipulation

• preparing the real-time MD simulation. After that we report on using this system for a new lateral manipulation methodology that we refer to as point contact pushing (PCP) technique, followed by a 3D trajectory that enabled us to lift in a controlled way a chain of gold atoms above a metal surface. These

• reproducible evolution to a symmetric structure of the second layer from the tip apex atom is reported [18]. Results and Discussion In this section we will show how the above system with the real-time MD simulation works using some simple lateral manipulation test followed by an experiment where we lifted a

• and the common lateral manipulation mode is that we do not move the tip in a straight path but we move from hollow site to hollow site by bringing the tip always in-line with the path to the next hollow site and then push the adatom. This is done so that the adatom position can be known and controlled

Manipulation studies of nanoparticles, with the aid of an AFM have shown that there is a contact-area dependence of the friction force. Several types of nanoparticles with reported diameters, such as latex spheres (80–100 nm) [28], Sb
