Abstract

Thermal desorption spectroscopy (TDS) and infrared reflection absorption spectroscopy under ultrahigh vacuum were used to study morphological change of amorphous ice films of D2O. Water molecules were evaporated onto a Ru substrate at 25 K and subjected to an annealing process at various temperatures. Two desorption species of methane were observed in TDS at low temperatures. Results showed that morphological change of amorphous ice induced by thermal relaxation took place in a stepwise manner.
