Graphene-Based Platform for Infrared Near-Field Nanospectroscopy of Water and Biological Materials in an Aqueous Environment
Omar Khatib, Joshua D. Wood, Alexander S. McLeod +12
Scattering scanning near-field optical microscopy (s-SNOM) has emerged as a powerful nanoscale spectroscopic tool capable of characterizing individual biomacromolecules and molecul…
Effective Passivation of Exfoliated Black Phosphorus Transistors against Ambient Degradation
Joshua D. Wood, Spencer A. Wells, Deep Jariwala +7
Unencapsulated, exfoliated black phosphorus (BP) flakes are found to chemically degrade upon exposure to ambient conditions. Atomic force microscopy, electrostatic force microscopy…
Scanning Tunneling Microscopy Study and Nanomanipulation of Graphene-Coated Water on Mica
Kevin T. He, Joshua D. Wood, Gregory P. Doidge +2
We study interfacial water trapped between a sheet of graphene and a muscovite (mica) surface using Raman spectroscopy and ultra-high vacuum scanning tunneling microscopy (UHV-STM)…
Matrix multiplication using quantum-dot cellular automata to implement conventional microelectronics
Joshua D. Wood, P. Douglas Tougaw
Quantum-dot cellular automata (QCA) shows promise as a post silicon CMOS, low power computational technology. Nevertheless, to generalize QCA for next-generation digital devices, t…
