Strong-field terahertz optical sideband generation for wavelength conversion in asymmetric double quantum wells
Terahertz (THz) optical sideband generation in asymmetric double quantum wells in strong THz fields is studied theoretically. Both monotonic THz-power dependence and saturation of the first-order sideband intensity can occur...

Nanoimprint lithography resist profile inversion for lift-off applications
A method is described in which the tapered features that are inherent to nanoimprint lithography are inverted to allow successful lift-off. A mold of the relief is created by in-filling the imprinted resist with hydrogen...

Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs
Philip A. Shields, Martin D. B. Charlton, Tom Lee, Majd E. Zoorob, Duncan W. E. Allsopp, Wang Nang Wang
Jul 01, 2009
The far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements...
Factors influencing surface morphology of anodized TiO 2 nanotubes
Domenico Regonini, A Satka, A Jaroenworaluck, Duncan W E Allsopp, Christopher R Bowen, R Stevens
Jan 01, 0001
This paper investigates the formation mechanism of ribs on the outer wall of anodized TiO 2 nanotubes (NTs) prepared in a NaF/Glycerol electrolyte containing 2 wt% of water. The effect of potential and time on the morphology of...

Waveguide integrated GaN distributed Bragg reflector cavity using low-cost nanolithography
Simeng Jia, Emmanuel D. Le Boulbar, Krishna C. Balram, Jon R. Pugh, Tao Wang, Duncan W.E. Allsopp, Philip A. Shields, Martin J. Cryan
Nov 20, 2019
This work presents the design, fabrication and measurement of gallium nitride (GaN) distributed Bragg reflector cavities integrated with input and output grating couplers. The devices are fabricated using a new, low-cost...
Progressive Recruitment of the Frontoparietal Multiple-demand System with Increased Task Complexity, Time Pressure, and Reward.
A distributed, frontoparietal "multiple-demand" (MD) network is involved in tasks of many different kinds. Integrated activity across this network may be needed to bind together the multiple features of a mental control program...

Did Somebody Say Augustan Totalitarianism? Duncan Kennedy’s ‘Reflections,’ Hannah Arendt’s $\textit{Origins}$, and the Continental Divide over Virgil’s $\textit{Aeneid}$
E Giusti
Feb 23, 2017
The allegedly old-fashioned debate over the pro- or anti- Augustanism of Augustan texts was superseded in 1992 by Duncan Kennedy’s ‘reflections’ over these terms of reference. Since then, the old dichotomy has appeared to be...
Evolution of the m-plane Quantum Well Morphology and Composition within a GaN/InGaN Core-Shell Structure
Pierre-marie Coulon, Shahrzad Hosseini-Vajargah, An Bao, Paul R. Edwards, Emmanuel Le Boulbar, Ionut Girgel, Robert W. Martin, Colin Humphreys, Rachel Oliver, Duncan Allsopp, Philip A. Shields
Feb 01, 2017
GaN/InGaN core–shell nanorods are promising for optoelectronic applications due to the absence of polarization-related electric fields on the sidewalls, a lower defect density, a larger emission volume, and strain relaxation at...
