Real-Time Observation of Exciton-Phonon Coupling Dynamics in Self-Assembled Hybrid Perovskite Quantum Wells
L Ni, U Huynh, A Cheminal, T Thomas, R Shivanna, T Hinrichsen, S Ahmad, A Sadhanala, A Rao
Sep 14, 2018
Self-assembled hybrid perovskite quantum wells have attracted attention due to their tunable emission properties, ease of fabrication and device integration. However, the dynamics of excitons in these materials, especially how...
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...

Nov 01, 2016
Objective Anti-nuclear autoantibodies are known to occur in 85-99% of Systemic Sclerosis (SSc) patients, with each SSc autoantibody correlating with a distinct clinical subset of patients. The objective of this study was to...
Multistable nematic wells
This review article is a consolidated but not exhaustive account of recent modelling and numerical work on nematic-filled square or cuboid shaped wells with planar degenerate boundary conditions. This seemingly simple...
Anomaly interplay in U(2) gauge theories
Abstract: We discuss anomaly cancellation in U(2) gauge theories in four dimensions. For a U(2) gauge theory defined with a spin structure, the vanishing of the bordism group Ω5Spin (BU(2)) implies that there can be no global...
Exchange interactions in Cd1-xMnxTe wide quantum wells
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...

Anomaly interplay in U(2) gauge theories
We discuss anomaly cancellation in $U(2)$ gauge theories in four dimensions.
For a $U(2)$ gauge theory defined with a spin structure, the vanishing of the
bordism group $\Omega_5^{\text{Spin}}(BU(2))$ implies that there can be...

Focus U-Net
BACKGROUND: Colonoscopy remains the gold-standard screening for colorectal cancer. However, significant miss rates for polyps have been reported, particularly when there are multiple small adenomas. This presents an opportunity...

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...
