Purely excitonic lasing in ZnO microcrystals: Temperature-induced transition between exciton-exciton and exciton-electron scattering [PDF]

open access: yes, 2017
Since the seminal observation of room-temperature laser emission from ZnO thin films and nanowires, numerous attempts have been carried out for detailed understanding of the lasing mechanism in ZnO.

Coulomb Oscillations of Indium-doped ZnO Nanowire Transistors in a Magnetic Field

open access: yes, 2010
We report on the observation of Coulomb oscillations from localized quantum dots superimposed on the normal hopping current in ZnO nanowire transistors. The Coulomb oscillations can be resolved up to 20 K.

Dynamics of ZnO nanowires immersed in in-plane switching liquid crystal cells

open access: yes, 2013
We investigated both numerically and experimentally the dynamics of individual ZnO nanowires immersed in an in-plane switching (IPS) 4-Cyano-4-pentylbiphenyl (5CB) liquid crystal cell under switching electric fields.

Spin-polarized electronic structure of the core-shell ZnO/ZnO:Mn nanowires probed by x-ray absorption and emission spectroscopy

open access: yes, 2013
The combination of x-ray spectroscopy methods complemented with theoretical analysis unravels the coexistence of paramagnetic and antiferromagnetic phases in the Zn_0.9Mn_0.1O shell deposited onto array of wurtzite ZnO nanowires. The shell is crystalline

Model for reflection and transmission matrices of nanowire end facets

open access: yes, 2011
Nanowires show a large potential for various electrooptical devices, such as light emitting diodes, solar cells and nanowire lasers. We present a direct method developed to calculate the modal reflection and transmission matrix at the end facets of a ...

High-Order Waveguide Modes in ZnO Nanowires

open access: yesNano Letters, 2007
We use tapered silica fibers to inject laser light into ZnO nanowires with diameters around 250 nm to study their waveguiding properties. We find that high-order waveguide modes are frequently excited and carry significant intensity at the wire surface.

Electrical tuning of spin splitting in Bi-doped ZnO nanowires

open access: yes, 2018
The effect of applying an external electric field on doping-induced spin-orbit splitting of the lowest conduction-band states in a bismuth-doped zinc oxide nanowire is studied by performing electronic structure calculations within the framework of ...
