Just a few hours of baking in a conventional lab oven transformed the mixture into a single atomic layer of zinc-oxide with a smattering of cobalt atoms sandwiched between layers of graphene. In a final step, the graphene is burned away, leaving behind just a single atomic layer of cobalt-...
To understand what they found, the researchers compared devices with one and seven layers of MoS2 and tested how well they behave as a photodetector, that is, how they are able to convert light into an electric current. They found that the device with one-layer MoS2 absorbs less light than...
the gases used in PE-ALD ensure the entire surface of a substrate is covered, no matter its shape or the complexity of its features. And the self-limiting reactions ensure that coverage takes place a single layer of molecules at a time—...
