High-resolution spectroscopy of G191-B2B in the extreme-ultraviolet

open access: yes, 2002
We report a high-resolution (R = 3000-4000) spectroscopic observation of the DA white dwarf G191-B2B in the extreme-ultraviolet band 220-245 Å.

Operation of a free-electron laser from the extreme ultraviolet to the water window [PDF]

open access: yes, 2007
We report results on the performance of a free-electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent extreme-ultraviolet radiation source have been measured.

Spin–orbit torque-assisted switching in magnetic insulator thin films with perpendicular magnetic anisotropy

open access: yesNature Communications, 2016
By virtue of strong spin-orbit coupling, a current-carrying heavy metal may generate a torque on the magnetization of an interfaced ferromagnetic metal.

Optical performance of LPP multilayer collector mirrors

open access: yes, 2022
Paper 832217The usable power and the collector optics lifetime of high-power extreme ultraviolet light sources at 13.5 nm are considered as the major challenges in the transitioning of EUV lithography from the current pre-production phase to high volume ...

Tailoring Photochromism Beyond Human Eye Visibility: On/Off Switchable NIR Absorption in an Aluminosilicate

open access: yesAngewandte Chemie, EarlyView.
A new photochromic material was developed. Its on/off‐switchable absorption band is situated completely outside the human eye's visibility, in the near‐infrared (NIR) region, a feature never reported before. The photochromism mechanism in this aluminosilicate is elucidated by combining experimental as well as computational results, and the material's ...

Research in extreme ultraviolet and far ultraviolet astronomy [PDF]

open access: yes, 1985
Instruments designed to explore different aspects of far and extreme ultraviolet cosmic radiation were studied. The far ultraviolet imager (FUVI) was flown on the Aries sounding rocket. Its unique large format 75mm detector mapped out the far ultraviolet

Nonthermal phase transitions in semiconductors induced by a femtosecond extreme ultraviolet laser pulse [PDF]

open access: yes, 2013
Part of Focus on High Energy Density Physics. In this paper, we present a novel theoretical approach, which allows the study of nonequilibrium dynamics of both electrons and atoms/ions within free-electron laser excited semiconductors at femtosecond time
