Journal ArticleDOI
Room-temperature continuous-wave lasing in GaN/InGaN microdisks
TL;DR: In this article, the authors report fabrication and optical measurements of GaN-based microdisk lasers with a very low threshold of 300 W cm−2, orders of magnitude lower than any previous GaN microdisk laser.
Journal ArticleDOI
Morphology of All-Solution-Processed “Bilayer” Organic Solar Cells
Kwan H. Lee,Paul E. Schwenn,Arthur R. G. Smith,Hamish Cavaye,Paul E. Shaw,Michael James,Karsten B. Krueger,Ian R. Gentle,Paul Meredith,Paul L. Burn +9 more
TL;DR: The evolution of the vertical morphology in a solution-processed P3HT/PCBM "bilayer" organic solar cell is investigated using a combination of techniques, including neutron reflectometry, and it is established that the solution processed bilayer concept is a misnomer.
Journal ArticleDOI
A Small Molecule Non‐fullerene Electron Acceptor for Organic Solar Cells
Paul E. Schwenn,Ke Gui,Alexandre M. Nardes,Karsten B. Krueger,Kwan H. Lee,Karyn Mutkins,Halina Rubinstein-Dunlop,Paul E. Shaw,Nikos Kopidakis,Paul L. Burn,Paul Meredith +10 more
TL;DR: In this paper, a new organic electron accepting small molecule 2-[{7-(9,9-di-n-propyl-9H-fluoren-2-yl)benzo[c][1,2,5]thiadiazol-4-yl}methylene]malononitrile (K12) was presented for organic solar cell applications.
Journal ArticleDOI
Cooling and control of a cavity optoelectromechanical system.
TL;DR: Out-of-loop transduction provides accurate temperature calibration even in the critical paradigm where measurement backaction induces optomechanical correlations, and 3 orders of magnitude improvement over any nanoelectromechanical system to date.
Journal ArticleDOI
Wavelength- and material-dependent absorption in GaAs and AlGaAs microcavities
C. P. Michael,Kartik Srinivasan,Thomas J. Johnson,Oskar Painter,Kwan H. Lee,K. Hennessy,Hyochul Kim,Evelyn L. Hu +7 more
TL;DR: In this article, the quality factors of GaAs and Al0.18Ga0.82As microdisks are tracked over three wavelength ranges centered at 980, 1460, and 1600 nm, with quality factors measured as high as 6.62×10^5 in the 1600 nm band.
