Hydrogen induced lattice expansion in 8/4 u.c. Mo/V superlattice

Abstract The hydrogen-induced lattice expansion in highly strained quasi two-dimensional V layers embedded in a Mo/V 8/4 u.c. superlattice has been studied in the temperature range 140–300 °C . Comparison to lower strained V layers showed a strong dependency of the strain on the lattice expansion. For c ≤0.5 the expansion was found to be lower than that for V-layers with lower initial strain. For c >0.5 the expansion was increased indicating a change in site occupancy.
