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...
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...
