Motion of in-channel dimers on W(112): A DFT study

► Mechanism of motion of in-channel addimers on the W(112) surface. ► Length of in-channel adatom-adatom interactions on the W(112) surface. ► Charge distribution for the nearest neighbor addimer on the W(112) surface. ► Response of the W(112) substrate on adsorption and motion of in-channel addimers.
