Journal ArticleDOI
Size-dependent light output, spectral shift, and self-heating of 400 nm InGaN light-emitting diodes
Zheng Gong,Shirong Jin,Yujie Chen,Jonathan J. D. McKendry,David Massoubre,Ian Watson,Erdan Gu,Martin D. Dawson +7 more
TL;DR: In this paper, the impact of device size scaling on the light output, spectral shift, and self-heating of 400 nm InGaN light-emitting diodes (LEDs) was systematically investigated.
Journal ArticleDOI
Strain and composition distributions in wurtzite InGaN/GaN layers extracted from x-ray reciprocal space mapping
Sérgio Pereira,Maria R. Correia,Eduarda Pereira,K.P. O'Donnell,Eduardo Alves,A.D. Sequeira,N. Franco,Ian Watson,C. J. Deatcher +8 more
TL;DR: In this article, the authors used high-resolution reciprocal space mapping (RSM) to detect composition and strain gradients independently from the elongation of broadened reciprocal lattice points in asymmetric x-ray reflections.

Sujan Rajbhandari,Sujan Rajbhandari,Jonathan J. D. McKendry,Johannes Herrnsdorf,Hyunchae Chun,Grahame Faulkner,Harald Haas,Ian Watson,Dominic O'Brien,Martin D. Dawson +9 more
TL;DR: The state-of-the-art technology enabling bandwidth of GaN LEDs in the range of >400 MHz is explored and advances in key technologies, including advanced modulation, equalisation, and multiplexing that have enabled free-space VLC data rates beyond 10 Gb/s are outlined.
