Spontaneous Polarisation Build up in a Room Temperature Polariton Laser
J. J. Baumberg, A. V. Kavokin, S. Christopoulos +9
We observe the build up of strong (~50%) spontaneous vector polarisation in emission from a GaN-based polariton laser excited by short optical pulses at room temperature. The Stoke…
Development of a Classical Force Field for the Oxidised Si Surface: Application to Hydrophilic Wafer Bonding
Daniel J. Cole, Mike C. Payne, Gabor Csanyi +2
We have developed a classical two- and three-body interaction potential to simulate the hydroxylated, natively oxidised Si surface in contact with water solutions, based on the com…
Resonant light delay in GaN with ballistic and diffusive propagation
T. V. Shubina, M. M. Glazov, A. A. Toropov +8
We report on a strong delay in light propagation through bulk GaN, detected by time-of-flight spectroscopy. The delay increases resonantly as the photon energy approaches the energ…
Scale decomposition of molecular beam epitaxy
Z. Moktadir
In this work, a study of epitaxial growth was carried out by means of wavelets formalism. We showed the existence of a dynamic scaling form in wavelet discriminated linear MBE equa…
Optical properties of Er3+ doped alkali-chloro phosphate glasses for optical amplifiers
K. Pradeesh, C. J. Oton, V. K. Agotiya +2
A new class of Erbium doped glasses with compositions xNa2O - (60-x)PbCl2 - 40P2O5 (x=0, 10, 20 and 30) were fabricated and characterized for optical properties. Absorption spectra…
Anisotropy of Magnetization Reversal and Magnetoresistance in Square Arrays of Permalloy Nano-Rings
A. V. Goncharov, A. A. Zhukov, V. V. Metlushko +8
Magnetization reversal mechanisms and impact of magnetization direction are studied in square arrays of interconnected circular permalloy nanorings using MOKE, local imaging, numer…
