In this study, tin sulfide thin films were obtained by atomic layer deposition (ALD) using Tetrakis(dimethylamino)tin (TDMASn, [(CH3)2N]4Sn) and hydrogen sulfide (H2S). The growth rate of the tin sulfides (SnSx) was shown to be highly dependent on the deposition temperature, and reaction times of 1 second for the TDMASn and H2S were required to reach the(More)
Introduction: Sand dunes cover about 5% of the land surface on Earth, and longitudinal ('seif') dunes, where the material accumulates in lanes oriented along the mean transport direction, are among the most common type of dune[1,2], covering half to two-thirds of sand seas. In contrast, they are among the least common dune-type on Mars [3]. The Cassini(More)
