Growth and characterization of hypothetical zinc-blende ZnO films on GaAs(001) substrates with ZnS buffer layers
A.B.M.A. Ashrafi,Akio Ueta,Adrian Avramescu,Hidekazu Kumano,Ikuo Suemune,Young-Woo Ok,Tae Yeon Seong +6 more
TL;DR: In this paper, the growth and characterization of zinc-blende ZnO on GaAs(001) substrates was reported, which showed bright band-edge luminescence at room temperature.
Journal ArticleDOI
Nitrogen-doped p-type ZnO layers prepared with H2O vapor-assisted metalorganic molecular-beam epitaxy
TL;DR: In this article, Nitrogen doping in ZnO was studied to realize reproducible p-type conductivity, and the results showed that the conversion from neutral donor-bound exciton emission in n-ZnO to neutral acceptor-bound emission in the p-ZNO layers showed consistent spectra with the electrical properties.
Journal ArticleDOI
Symmetric quantum dots as efficient sources of highly entangled photons: Violation of Bell's inequality without spectral and temporal filtering
Takashi Kuroda,Takaaki Mano,Neul Ha,Hideaki Nakajima,Hidekazu Kumano,Bernhard Urbaszek,Masafumi Jo,Marco Abbarchi,Yoshiki Sakuma,Kazuaki Sakoda,Ikuo Suemune,Xavier Marie,Thierry Amand +12 more
TL;DR: In this paper, an ideal emitter of entangled photon pairs combined the perfect symmetry of an atom with the convenient electrical trigger of light sources based on semiconductor quantum dots was proposed.
Nitrogen-Doped p-Type ZnO Layers Prepared with H2O Vapor-Assisted
TL;DR: In this paper, the reproducibility of the p-type conductivity in ZnO is investigated and it is shown that the performance of the N-doped layers depends critically on the stoichiometric control of the growth parameters of the n-junction diode.
Journal ArticleDOI
