The threshold photoelectron spectrum of mercury [PDF]

open access: yes, 2013
The threshold photoelectron spectrum of mercury has been recorded over the energy range (10–40 eV) which covers the region from the lowest state of the singly charged ion,5d106s(2S1/2), to the double charged ionic state, 5d9(2D3/2)6s(1D2).

Numerical study of an electrowetting liquid microlens

open access: yesAIP Advances, 2018
We construct a numerical model for a liquid microlens formed by filling a microwell with two immiscible liquids, namely oil and water. The water–oil interface can be actuated as a tunable liquid lens because its curvature is well controlled by applying ...

Mechanism of Perfluoropolyether Chains Bonding on Carbon Overcoat Surface by Ultraviolet Irradiation

open access: yesTribology Online, 2009
To elucidate the bonding mechanism of a non-polar perfluoropolyether lubricant (PFPE lube) under ultraviolet (UV) irradiation, the UV wavelength ranges in which photoelectrons emanate were identified using photoelectron spectroscopy in air (PESA), and ...

Effects of Inclined Sidewall Structure With Bottom Metal Air Cavity on the Light Extraction Efficiency for AlGaN-Based Deep Ultraviolet Light-Emitting Diodes

open access: yesIEEE Photonics Journal, 2017
An inclined sidewall scattering structure with air cavity characterized by a metal bottom and flat parallel top (Bottom_metal) is proposed to enhance the light extraction efficiency (LEE) for AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs).
