Hydrogen Diffusion and Stabilization in Single-Crystal VO2 Micro/Nanobeams by Direct Atomic Hydrogenation
Lin, Jian; Ji, Heng; Swift, Michael W.; Hardy, Will J.; Peng, Zhiwei; Fan, Xiujun; Nevidomskyy, Andriy H.; Tour, James M.; Natelson, Douglas (2014)We report measurements of the diffusion of atomic hydrogen in single crystalline VO2 micro/nanobeams by direct exposure to atomic hydrogen, without catalyst. The atomic hydrogen is generated by a hot filament, and the ... -
In Situ Diffraction Study of Catalytic Hydrogenation of VO2: Stable Phases and Origins of Metallicity
Filinchuk, Yaroslav; Tumanov, Nikolay A.; Ban, Voraksmy; Ji, Heng; Wei, Jiang; Swift, Michael W.; Nevidomskyy, Andriy H.; Natelson, Douglas (2014)Controlling electronic population through chemical doping is one way to tip the balance between competing phases in materials with strong electronic correlations. Vanadium dioxide exhibits a first-order phase transition ... -
In situ imaging of the conducting filament in a silicon oxide resistive switch
Yao, Jun; Zhong, Lin; Natelson, Douglas; Tour, James M. (2012)The nature of the conducting filaments in many resistive switching systems has been elusive. Throughᅠin situᅠtransmission electron microscopy, we image the real-time formation and evolution of the filament in a silicon ... -
Nanostructure investigations of nonlinear differential conductance in NdNiO3 thin films
Hardy, Will J.; Ji, Heng; Mikheev, Evgeny; Stemmer, Susanne; Natelson, Douglas (2014)Transport measurements on thin films of NdNiO3 reveal a crossover to a regime of pronounced nonlinear conduction below the well-known metal-insulator transition temperature. The evolution of the transport properties at ... -
Shot noise detection in hBN-based tunnel junctions
Zhou, Panpan; Hardy, Will J.; Watanabe, Kenji; Taniguchi, Takashi; Natelson, Douglas (2017)High quality Au/hBN/Au tunnel devices are fabricated using transferred atomically thin hexagonal boron nitride as the tunneling barrier. All tunnel junctions show tunneling resistance on the order of several kΩ/μm2. Ohmic ... -
Thermally driven analog of the Barkhausen effect at the metal-insulator transition in vanadium dioxide
Huber-Rodriguez, Benjamin; Kwang, Siu Yi; Hardy, Will J.; Ji, Heng; Chen, Chih-Wei; Morosan, Emilia; Natelson, Douglas (2014)The physics of the metal-insulator transition (MIT) inᅠvanadiumᅠdioxide remains a subject of intense interest. Because of the complicating effects of elastic strain on the phase transition, there is interest in comparatively ... -
Thermoplasmonics: Quantifying Plasmonic Heating in Single Nanowires
Herzog, Joseph B.; Knight, Mark W.; Natelson, Douglas (2014)Plasmonic absorption of light can lead to significant local heating in metallic nanostructures, an effect that defines the sub-field of thermoplasmonics and has been leveraged in diverse applications from biomedical ... -
Voltage tuning of vibrational mode energies in single-molecule junctions
Li, Yajing; Doak, Peter; Kronik, Leeor; Neaton, Jeffrey B.; Natelson, Douglas (2014)Vibrational modes of molecules are fundamental properties determined by intramolecular bonding, atomic masses, and molecular geometry, and often serve as important channels for dissipation in nanoscale processes. Although ...
