  • Double-layer ice from first principles 

    Chen, J; Schusteritsch, G; Pickard, CJ; Salzmann, CG; Michaelides, A (American Physical Society, 2017-03-31)
    The formation of monolayer and multilayer ice with a square lattice structure has recently been reported on the basis of transmission electron microscopy experiments, renewing interest in confined two-dimensional ice. Here ...
  • Low-Loss MMICs Viable Transmission Media for GaN-on-Low Resistivity Silicon Technology 

    Eblabla, A; Benakaprasad, B; Li, X; Wallis, DJ; Guiney, I; Elgaid, K (IEEE, 2017-01-01)
    In this work a novel ultra-low loss transmission media for RF GaN-on-low-resistivity silicon (LR-Si) substrates (σ < 40 $\Omega$.cm) has been successfully demonstrated. The developed shielded-microstrip lines achieve ...
  • GaN on Low-Resistivity Silicon THz High-Q Passive Device Technology 

    Eblabla, AM; Li, X; Wallis, DJ; Guiney, I; Elgaid, K (IEEE, 2017-01-01)
    In this paper, viable transmission media technology has been demonstrated for the first time on GaN on low-resistivity silicon) substrates (ρ < 40 $\Omega$·cm) at H-band frequencies (220-325 GHz). The shielded-elevated ...
  • Wafer-scale Fabrication of Non-Polar Mesoporous GaN Distributed Bragg Reflectors via Electrochemical Porosification 

    Zhu, T; Liu, Y; Ding, T; Fu, WY; Jarman, J; Ren, CX; Kumar, RV et al. (Nature Publishing Group, 2017-03-27)
    Distributed Bragg reflectors (DBRs) are essential components for the development of optoelectronic devices. For many device applications, it is highly desirable to achieve not only high reflectivity and low absorption, but ...
