Microsecond Valley Lifetime of Defect-Bound Excitons in Monolayer WSe
Galan Moody, Kha Tran, Xiaobo Lu +6
In atomically thin two-dimensional semiconductors such as transition metal dichalcogenides (TMDs), controlling the density and type of defects promises to be an effective approach…
Independence of Optical Absorption on Auger Ionization in Single-Walled Carbon Nanotubes Revealed by Ultrafast e-h Photodoping
Mitchell D. Anderson, Meghan N. Beattie, Jack A. Alexander-Webber +2
Auger-ionized carriers in a one-dimensional semiconductor are predicted to result in a strong band-gap renormalization. Isolated single-walled carbon nanotubes (SWCNT) under high-i…
Fully-automatic laser welding and micro-sculpting with universal in situ inline coherent imaging
Paul J. L. Webster, Logan G. Wright, Yang Ji +4
Though new affordable high power laser technologies make possible many processing applications in science and industry, depth control remains a serious technical challenge. Here we…
First-passage theory of exciton population loss in single-walled carbon nanotubes reveals micron-scale intrinsic diffusion lengths
Mitchell Anderson, Yee-fang Xiao, James M. Fraser
One-dimensional crystals have long range translational invariance which manifests as long exciton diffusion lengths, but such intrinsic properties are often obscured by environment…
Photoluminescence clamping with few excitons in a single-walled carbon nanotube
Y. -F. Xiao, T. Q. Nhan, M. W. B. Wilson +1
Single air-suspended carbon nanotubes (length 2 - 5 microns) exhibit high optical quantum efficiency (7 - 20%) for resonant pumping at low intensities. Under ultrafast excitation,…
