Probing nanoscale thermal transport with cathodoluminescence thermometry
Kelly W. Mauser, Magdalena Solà-Garcia, Matthias Liebtrau +6
Thermal properties have an outsized impact on efficiency and sensitivity of devices with nanoscale structures, such as in integrated electronic circuits. A number of thermal conduc…
Strain evolution in GaN Nanowires: from free-surface objects to coalesced templates
M. Hugues, P. A. Shields, F. Sacconi +7
Top-down fabricated GaN nanowires, 250 nm in diameter and with various heights, have been used to experimentally determine the evolution of strain along the vertical direction of 1…
Superlattice Magnetophonon Resonances in Strongly Coupled InAs/GaSb Superlattices
R. S. Deacon, A. B. Henriques, R. J. Nicholas +1
We report an experimental study of miniband magnetoconduction in semiconducting InAs/GaSb superlattices. For samples with miniband widths below the longitudinal optical phonon ener…
Free carrier effects in gallium nitride epilayers: the valence band dispersion
P. A. Shields, R. J. Nicholas, F. M. Peeters +2
The dispersion of the A-valence-band in GaN has been deduced from the observation of high-index magneto-excitonic states in polarised interband magneto-reflectivity and is found to…
Magneto-photoluminescence of GaN/AlGaN quantum wells: valence band reordering and excitonic binding energies
P. A. Shields, R. J. Nicholas, N. Grandjean +1
A re-ordered valence band in GaN/AlGaN quantum wells with respect to GaN epilayers has been found as a result of the observation of an enhanced g-factor in magneto-luminescence spe…
