Quantum tunneling in the surface diffusion of single hydrogen atoms on Cu(001)

“…[1,2] The diffusion of hydrogen atoms on metal surfaces is an important step in many catalytic reactions, such as the formation of ammonia in the Haber-Bosch process, [3] the synthesis of hydrocarbons, [4] and the generation and oxidation of H 2 in electrochemistry. [5,6] Numerous experimental [7][8][9][10][11][12] and theoretical [13][14][15][16][17][18][19] studies have been carried out to understand the process of hydrogen diffusion on solid surfaces. Experimental techniques such as helium atom scattering (HAS), [9] scanning tunneling microscopy (STM), [10,11] inelastic electron tunneling spectroscopy (IETS), [10,11] high-resolution electron energy loss spectroscopy (HREELS), [20] and linear optical diffraction (LOD) techniques [7] have been used to study the quantum effects of hydrogen atoms during diffusion.…”
