SANTA: Self-Aligned Nanotrench Ablation via Joule Heating for Probing Sub-20 nm Devices
Feng Xiong, Sanchit Deshmukh, Sungduk Hong +4
Manipulating materials at the nanometer scale is challenging, particularly if alignment with nanoscale electrodes is desired. Here we describe a lithography-free, self-aligned nano…
Nanoscale Phase Change Memory with Graphene Ribbon Electrodes
Ashkan Behnam, Feng Xiong, Andrea Cappelli +9
Phase change memory (PCM) devices are known to reduce in power consumption as the bit volume and contact area of their electrodes are scaled down. Here, we demonstrate two types of…
Annealing Free, Clean Graphene Transfer using Alternative Polymer Scaffolds
Joshua D. Wood, Gregory P. Doidge, Enrique A. Carrion +11
We examine the transfer of graphene grown by chemical vapor deposition (CVD) with polymer scaffolds of poly(methyl methacrylate) (PMMA), poly(lactic acid) (PLA), poly(phthalaldehyd…
Hysteresis-Free Nanosecond Pulsed Electrical Characterization of Top-Gated Graphene Transistors
Enrique A. Carrion, Andrey Y. Serov, Sharnali Islam +6
We measure top-gated graphene field effect transistors (GFETs) with nanosecond-range pulsed gate and drain voltages. Due to high-k dielectric or graphene imperfections, the drain c…
High-Field Electrical and Thermal Transport in Suspended Graphene
Vincent E. Dorgan, Ashkan Behnam, Hiram J. Conley +2
We study the intrinsic transport properties of suspended graphene devices at high fields (>1 V/um) and high temperatures (>1000 K). Across 15 samples, we find peak (average) satura…
Transport in Nanoribbon Interconnects Obtained from Graphene Grown by Chemical Vapor Deposition
Ashkan Behnam, Austin S. Lyons, Myung-Ho Bae +4
We study graphene nanoribbon (GNR) interconnects obtained from graphene grown by chemical vapor deposition (CVD). We report low- and high-field electrical measurements over a wide…
Optimizing Transistor Performance of Percolating Carbon Nanotube Networks
V. K. Sangwan, A. Behnam, V. W. Ballarotto +3
In percolating networks of mixed metallic and semiconducting CNTs, there is a tradeoff between high on-current (dense networks) and high on/off ratio (sparse networks in which the…
