Femtosecond laser creates nanoelectronics on graphene

Mon, 07/30/2018 - 11:54
Traditional CMOS technology cannot be directly merged with graphene applications. Photo- and electron-based lithographies, which are the main processess in today's semiconductor industry, requires use of polymers and harsh liquids that can drastically alter the initial properties of graphene. Thus graphene requires the development of novel processing technologies. A international team of researchers now has developed a method for direct, on-the-fly reconstruction of graphene properties.

On the edge: turning graphene into a molecular toggle switch

Fri, 07/27/2018 - 09:29
An international team of researchers has discovered a new mechanism for controlling electronic devices using molecules. The ferroelectric ordering of polar molecules attached to the edge of graphene can be toggle-switched by an electrostatic gate and can be used for memory devices and sensors. For this work, the team sandwiched graphene layers in hexagonal boron nitride crystals. The trick is to control the edge chemistry. The researchers attached different atoms to the graphene edges, before exposing them to water vapor and other polar molecules.
