DESCRIPTION:Prof. Igor Aharonovich\, University of Technology\, Sydney (AU
 S)\nBIOENGINEERING SEMINAR\n\nAbstract:\nEngineering solid state quantum s
 ystems is amongst grand challenges in engineering quantum information proc
 essing systems. While several 3D systems (such as diamond\, silicon carbid
 e\, zinc oxide) have been thoroughly studied\, solid state emitters in two
  dimensional (2D) materials have not been observed. 2D materials are becom
 ing major players in modern nanophotonics technologies and engineering qua
 ntum emitters in these systems is a vital goal.\n\nIn this talk I will dis
 cuss the recently discovered single photon emitters in 2D hexagonal boron 
 nitride (hBN). I will present several avenues to engineer these emitters i
 n large exfoliated sheets using ion and electron beam techniques. Density 
 functional theory calculations suggest that the studied defects are the an
 tisite nitrogen vacancy in hBN. The formed emitters in 2D hBN flakes have 
 extremely promising properties – including high brightness (~ millions c
 ounts/s)\, stability up to high temperatuers and linear polarization at ex
 citation and absorption. Those properties make these emitters extremely at
 tractive for their integration with optical resonators and waveguides. Fin
 ally\, I will discuss several challenges and promising directions in the f
 ield of quantum emitters and nanophotonics with 2D materials and other wid
 e band gap materials.\n\nBio:\nIgor Aharonovich received his PhD in 2010 f
 rom the University of Melbourne and spent two years in Harvard as a postdo
 ctoral researcher in the group of Prof Evelyn Hu. In 2013 Igor returned to
  Australia and joined the School of Mathematical and Physical Sciences\, U
 niversity of Technology Sydney (UTS)\, where he is currently an Associate 
 Professor and the leader of the Nanophotonics laboratory.\nDr. Aharonovich
 ’s group is focusing on exploring single emitters in wide band gap semic
 onductors\, and their implementation in quantum technologies and bio-medic
 al applications. His group is also interested in innovative approaches for
  nanofabrication of nanophotonics devices for low threshold lasing and ene
 rgy efficient light sources.\nDr. Aharonovich is a recipient of the IEEE Y
 oung Investigator Award (2016\, honors an individual who has made outstand
 ing technical contributions to photonics prior to 35th birthday)\, The 201
 7 IUPAP Young Scientist Award (Commission on Laser Physics and Photonics) 
 and the 2017 Pawsey medal from the Australian Academy of Science.\n
