    • Direct Injection Tunnel Spectroscopy of a p-n Junction 

      Likovich, Edward Michael; Russell, Kasey Joe; Narayanamurti, Venkatesh; Lu, Hong; Gossard, Arthur C. (American Institute of Physics, 2009)
      We demonstrate spectroscopic measurements on an InGaAs p-n junction using direct tunnel injection of electrons. In contrast to the metal-base transistor design of conventional ballistic electron emission spectroscopy (BEES), ...
    • Epitaxial Catalyst-Free Growth of InN Nanorods on c-Plane Sapphire 

      Shalish, Ilan; Seryogin, G.; Yi, W.; Bao, J. M.; Zimmler, M. A.; Likovich, Edward Michael; Bell, David C.; Capasso, Federico; Narayanamurti, Venkatesh (Springer-Verlag, 2009)
      We report observation of catalyst-free hydride vapor phase epitaxy growth of InN nanorods. Characterization of the nanorods with transmission electron microscopy, and X-ray diffraction show that the nanorods are stoichiometric ...
    • Growth of ZnO Nanowires Catalyzed by Size-Dependent Melting of Au Nanoparticles 

      Petersen, Eric W.; Likovich, Edward Michael; Russell, Kasey Joe; Narayanamurti, Venkatesh (Institute of Physics, 2009)
      We present a general approach to growing ZnO nanowires on arbitrary, high melting point (above 970 °C) substrates using the vapor–liquid–solid (VLS) growth mechanism. Our approach utilizes the melting point reduction of ...
    • High-Current-Density Monolayer CdSe/ZnS Quantum Dot Light-Emitting Devices with Oxide Electrodes 

      Likovich, Edward; Jaramillo, Rafael; Russell, Kasey Joe; Ramanathan, Shriram; Narayanamurti, Venkatesh (Wiley-Blackwell, 2011)
    • Magnetoresistance in an Asymmetric GaMnAs Resonant Tunneling Diode 

      Likovich, Edward Michael; Russell, Kasey Joe; Yi, Wei; Narayanamurti, Venkatesh; Ku, Keh-Chiang; Zhu, Meng; Samarth, Nitin (American Physical Society, 2009)
      In a GaMnAs/AlGaAs resonant tunneling diode (RTD) structure, we observe that both the magnitude and polarity of magnetoresistance are bias dependent when tunneling from a three-dimensional GaMnAs layer through a two-dimensional ...
    • Weak Localization and Mobility in ZnO Nanostructures 

      Likovich, Edward Michael; Russell, Kasey Joe; Petersen, Eric W.; Narayanamurti, Venkatesh (American Physical Society, 2009)
      We conduct a comprehensive investigation into the electronic and magnetotransport properties of ZnO nanoplates grown concurrently with ZnO nanowires by the vapor-liquid-solid method. We present magnetoresistance data showing ...
