  • Stevens-Kalceff, Marion; Prawer, S; Kalceff, Walter; Orwa, J; Peng, J; Mccallum, Jeffrey; Jamieson, David (American Institute of Physics, 2008)
    MeV carbon ion implantation followed by thermal annealing in a hydrogen-containing atmosphere produces a layer of diamond nanocrystals within fused quartz (SiO2). Cathodoluminescence (CL) microanalysis in a scanning electron ...
  • Stacey, A; Aharonovich, Igor; Prawer, S; Butler, James (Elsevier B.V., 2009)
    Diamond containing engineered color centers is rapidly becoming a medium of choice for quantum information applications. Many of the dramatic recent results in this field have been demonstrated in diamond nano-crystals. ...
  • Aharonovich, Igor; Castelletto, S; Simpson, D; Su, C-H; Greentree, A; Prawer, S (IOP Publishing, 2011)
    The exploitation of emerging quantum technologies requires efficient fabrication of key building blocks. Sources of single photons are extremely important across many applications as they can serve as vectors for quantum ...
  • Aharonovich, Igor; Castelletto, S; Johnson, B; Mccallum, J; Prawer, S (IOP Publishing Ltd, 2011)
    Color centers in diamond, as single photon emitters, are leading candidates for future quantum devices due to their room temperature operation and photostability. The recently discovered chromium-related centers are ...
  • Aharonovich, Igor; Zhou, Chunyuan; Stacey, A; Orwa, J; Castelletto, S; Simpson, D; Greentree, Andrew; Treussart, F; Roch, Jean-Francois; Prawer, S (Amer Physical Soc, 2009)
    Individual color centers in diamond are promising for near-term quantum technologies including quantum key distribution and metrology. Here we show fabrication of an as-yet uncharacterized nickel-related complex in diamond ...
  • Aharonovich, Igor; Prawer, S (Elsevier B.V., 2010)
    Color centers in diamond attract a major attention due to their potential use in quantum information processing. In this work several methodologies to fabricate diamond based single photon emitters are presented: Ion ...
  • Aharonovich, Igor; Zhou, Chunyuan; Stacey, A; Treussart, F; Roch, Jean-Fran??Ois; Prawer, S (Amer Inst Physics, 2008)
    A technique to create nickel-related single color centers in individual nanodiamonds is demonstrated. The method involves implantation of nickel ions into a substrate onto which the diamond nanocrystals are subsequently ...
  • Siyushev, P; Jacques, V; Aharonovich, Igor; Kaiser, F; Muller, T.; Lombez, L; Atature, Mete; Castelletto, S; Prawer, S; Jelezko, F; Wrachtrup, J (Institute of Physics (UK), 2009)
    In this paper, we study the optical properties of single defects emitting in the near infrared (NIR) in nanodiamonds at liquid helium temperature. The nanodiamonds are synthesized using a microwave chemical vapor deposition ...
  • Kennard, J; Hadden, J; Marseglia, L; Aharonovich, Igor; Castelletto, S; Patton, B; Politi, A; Matthews, J; Sinclair, A; Gibson, B.; Prawer, S; Rarity, J; O'Brien, J (APS, 2013)
    Operating reconfigurable quantum circuits with single photon sources is a key goal of photonic quantum information science and technology. We use an integrated waveguide device containing directional couplers and a ...
  • Fang, Jinghua; Aharonovich, Igor; Leychenko, I; Ostrikov, K; Spizzirri, Paul; Rubanov, S; Prawer, S (Amer Chemical Soc, 2012)
    We report the catalyst-free synthesis of the arrays of core-shell, ultrathin, size-uniform SiC/AlSiC nanowires on the top of a periodic anodic aluminum oxide template. The nanowires were grown using an environmentally ...
  • Aharonovich, Igor; Santori, C; Fairchild, Barbara; Orwa, J; Ganesan, K; Fu, Kai-Mei; Beausoleil, Raymond; Greentree, Andrew; Prawer, S (Amer Inst Physics, 2009)
    Quantum information applications place stringent demands on the development of platforms that can host them. Color centers in diamond have been identified as important media for quantum information processing. Accordingly, ...
  • Aharonovich, Igor; Castelletto, S; Simpson, David; Stacey, A; Mccallum, J; Greentree, Andrew; Prawer, S (Amer Chemical Soc, 2009)
    The fabrication of stable ultrabright single photon sources operating at room temperature Is reported. The emitter is based on a color center within a diamond nanocrystal grown on a sapphire substrate by chemical vapor ...
  • Muller, T.; Aharonovich, Igor; Lombez, L; Alaverdyan, Y; Vamivakas, A; Castelletto, S; Jelezko, F; Wrachtrup, J; Prawer, S; Atature, Mete (Institute of Physics (UK), 2011)
    We demonstrate electrical control of the single-photon emission spectrum from chromium-based colour centres implanted in monolithic diamond. Under an external electric field, the tunability range is typically three orders ...
