Abundant Li resources in the ocean are promising alternatives to refining ore, whose supplies are limited by the total amount and geopolitical imbalance of reserves in Earth's crust. Despite advances in Li+ extraction using porous membranes, they require screening other cations on a large scale due to the lack in precise control of pore size and inborn defects. Herein, MoS2 nanoflakes on a multilayer...
We investigated the effects of oxygen in amorphous silicon (a-Si) and polycrystalline silicon (poly-Si) thin films using excimer laser annealing (ELA). The dehydrogenation process prior to ELA was performed in air and N2 ambient, which was the method controlled oxygen content in a-Si thin films. We observed that the thin film of oxygen controlled process had lower oxygen concentration and oxidized...
The reliability properties of NOR flash memory with 65nm node being developed in Samsung electronics are greatly improved by using the newly proposed re-oxidized tunnel oxide. Especially, by optimizing the process variables such as the re-oxidation thickness/time, the partial pressure of NO during annealing, and the kinds of re-oxidizing materials, the Vth shifts post cycling and after post-cycling...
