(Invited) Harnessing Graphene Nanoribbons and Hexagonal Boron Nitride for Next-Generation Nanoelectronics and Photovoltaics

Robert M. Jacobberger, Jam Riyan Hamza, Ruixuan Liu, Chris Barns

This talk will present our group’s recent work on engineering semiconducting graphene nanoribbon arrays and inorganic/organic mixed-dimensional heterostructures to realize next-generation nanoelectronics and photovoltaics. First, arrays of aligned semiconducting graphene nanoribbons with sub-5-nm widths and well-defined edges promise to meet the demands …

Floating Body Cell with Independently-Controlled Double Gates for High Density Memory

Ibrahim Ban, Uygar E. Avci, Uday Shah, Chris Barns et autres

An aggressively scaled, self-aligned, independently controlled double-gate floating body cell (IDG FBC) is reported. This structure eases the scaling constraints of other FBC memory devices proposed to date. Enhanced memory performance has been demonstrated owing to the independent back gate with thin …

Viewing Asperity Behavior under the Wafer during CMP

Caprice Gray, Daniel Apone, Chris Rogers, Vincent P. Manno et autres

Recent experimental advances using dual emission laser induced fluorescence and image processing have provided high spatial and temporal resolution maps of the slurry layer during chemical mechanical polishing (CMP). Intensity differences in the images correspond to fluid layer thickness variations as the …
