CLEO®/Europe - EQEC 2015, an indium tin oxide metamaterial filter for the terahertz regime: Design, fabrication and characterization

Takan, Taylan; Nebioğlu, Mehmet Ali; Kurt, Metin; Demirhan, Yasemin; Özyüzer, Lütfi; Sabah, C.; Altan, Hakan (Optical Society of America (OSA), 2019)

Metamaterials are novel structures that show unique optical properties and promise applications such as perfect lenses, filters, invisibility cloaks and antennas [1, 2]. Various metamaterial structures with different metals ...

Reversible energy transfer between a single defect in HBN and graphene

Özçeri, Elif; Arı, Ozan; Balcı, Sinan; Kocabaş, Çoşkun; Ateş, Serkan (OSA - The Optical Society, 2019)

We present a reversible energy transfer between a single defect in hBN and graphene. Dynamic control of Fermi level of graphene results in switching on and off single photon emission from a single quantum emitter. © OSA ...

Influence of electron-phonon interactions on the spectral properties of defects in hexagonal boron nitride

Arı, Ozan; Fırat, Volkan; Polat, Nihat; Çakır, Özgür; Ateş, Serkan (OSA - The Optical Society, 2019)

We present temperature-dependent micro-PL studies on a single defect in hexagonal boron nitride. A zero-phonon line emission accompanied by Stokes and anti-Stokes phonon sidebands (˜ 6.5 meV) with a Debye-Waller factor of ...

Mini-review: "Ball-type phthalocyanines": Similarities and differences from mono phthalocyanines

Göl, Emre Yusuf; Karabudak, Engin (Bentham Science, 2019)

Ball-type phthalocyanines are recently synthesized binuclear derivatives of the widely known phthalocyanine molecule. In the ball-type Pc molecule, two cofacially arranged Pc rings have four bridged substituents on the ...
