Stratigraphy of Aeolis Dorsa, Mars: stratigraphic context of the great river deposits [PDF]

Icarus (2015), 253, 223-242, 2017
Unraveling the stratigraphic record is the key to understanding ancient climate and past climate changes on Mars. River deposits when placed in stratigraphic order could constrain the number, magnitudes, and durations of the wettest climates in Mars history. We establish the stratigraphic context of river deposits in Aeolis Dorsa sedimentary basin, 10E

Atomic layer deposition of Y2O3 on h-BN for a gate stack in graphene FETs [PDF]

Nanotechnology, 2015, 26, 175708, 2015
The combination of h-BN and high-k dielectrics is required for a top gate insulator in miniaturized graphene field-effect transistors because of the low dielectric constant of h-BN. We investigated the deposition of Y2O3 on h-BN using atomic layer deposition. The deposition of Y2O3 on h-BN was confirmed without any buffer layer.
