C. Rice, L. C. Smith, J. J. Davies, D. Wolverson, M. Wiater, G. Karczewski, T. Wojtowicz
Oct 24, 2012
The exchange interactions between excitons and manganese ions in wide (80 nm) quantum wells of Cd1−xMnxTe (x≈0.0015 and x≈0.00027) have been measured for states with center of mass quantum numbers up to 10. The corresponding...

Photoluminescence efficiency of zincblende InGaN/GaN quantum wells
SA Church, M Quinn, K Cooley-Greene, B Ding, A Gundimeda, MJ Kappers, M Frentrup, DJ Wallis, RA Oliver, DJ Binks
May 10, 2021
Growing green and amber emitting InGaN/GaN quantum wells in the zincblende, rather than the wurtzite, crystal phase has the potential to improve efficiency. However, optimization of the emission efficiency of these...
Order reconstruction patterns in nematic liquid crystal wells
We numerically study structural transitions inside shallow sub-micrometre scale wells with square cross section, filled with nematic liquid crystal material. We model the wells within the Landau–de Gennes theory. We obtain two...

Inversion asymmetry effects in modulation-doped Cd1-xMnxTe quantum wells
Caitlin Rice, D Wolverson, A Moskalenko, S J Bending, Gregorsz Karczewski, Tomek Wojtowicz
Mar 25, 2013
We report a striking in-plane anisotropy of the spin-flip Raman signals observed for dilute magnetic Cd1-xMnxTe quantum wells containing a two-dimensional electron gas. The effect depends upon electron concentration, which can...
