Effects of Tip-Nanotube Interactions on Atomic Force Microscopy Imaging of Carbon Nanotubes
Rouholla Alizadegan, Albert D. Liao, Feng Xiong +2
We examine the effect of van der Waals (vdW) interactions between atomic force microscope (AFM) tips and individual carbon nanotubes (CNTs) supported on SiO2. Molecular dynamics (M…
Electrical power dissipation in carbon nanotubes on single crystal quartz and amorphous SiO2
Cheng-Lin Tsai, Albert Liao, Eric Pop +1
Heat dissipation in electrically biased semiconducting carbon nanotubes (CNTs) on single crystal quartz and amorphous SiO2 is examined with temperature profiles obtained by spatial…
Thermally-Limited Current Carrying Ability of Graphene Nanoribbons
Albert D. Liao, Justin Z. Wu, Xinran Wang +4
We investigate high-field transport in graphene nanoribbons (GNRs) on SiO2, up to breakdown. The maximum current density is limited by self-heating, but can reach >3 mA/um for GNRs…
Thermal Dissipation and Variability in Electrical Breakdown of Carbon Nanotube Devices
Albert Liao, Rouholla Alizadegan, Zhun-Yong Ong +3
We study high-field electrical breakdown and heat dissipation from carbon nanotube (CNT) devices on SiO2 substrates. The thermal "footprint" of a CNT caused by van der Waals intera…
Inducing Chalcogenide Phase Change with Ultra-Narrow Carbon Nanotube Heaters
Feng Xiong, Albert Liao, Eric Pop
Carbon nanotube (CNT) heaters with sub-5 nm diameter induce highly localized phase change in Ge2Sb2Te5 (GST) chalcogenide. A significant reduction in resistance of test structures…
Reduction of Hysteresis for Carbon Nanotube Mobility Measurements Using Pulsed Characterization
David Estrada, Sumit Dutta, Albert Liao +1
We describe a pulsed measurement technique to suppress hysteresis for carbon nanotube (CNT) device measurements in air, vacuum, and over a wide temperature range (80-453 K). Varyin…
