Presentations

Light for the Nanoworld – Applications of EUV Compact Sources in Future Lithography and Metrology (AM4Q.1)
Presenter: Larissa Juschkin, Forschungszentrum Jülich, KLA Corporation

Sources of extreme ultraviolet and soft x-ray radiation enable manufacturing and probing nanostructures in 3D with natural contrast, that is crucial for nm-scale lithography, inspection and metrology. This talk highlights imaging applications with laboratory sources.

GaAs Detector Array for Soft X-ray Beam Position Monitoring in Storage Ring Light Sources (AM4Q.2)
Presenter: Jinghe Liu, Stony Brook University

We describe a GaAs detector array for soft-Xray photons with energies above 250 eV designed to operate with power density levels of up to 20 W/mm2 to be used in a novel beam position monitor.

  Paper

Ultra Close Range Localized Surface Plasmon Coupling With Multiple Quantum Well Towards Photoluminescence Intensity Enhancement of Micro-LED (AM4Q.3)
Presenter: Zaifa Du, Beijing University Of Technology

A strategy for the application of localized surface plasmon to Micro-LED is proposed in this paper. The quantum wells region is exposed by direct etching and Ag nanoparticles is used to generate localized surface plasmon.

  Paper

Demonstration of Tunable High Q Aluminum Nitride on Sapphire Microring Resonator at Green and UV Wavelengths (AM4Q.4)
Presenter: Walter Shin, University of Michigan

We demonstrate aluminum nitride on sapphire microring resonators at green and ultraviolet wavelength and measured record high quality factors of 147,000 at 532nm and 25,500 at 369.5nm based on thermo optic-effect.

  Paper

Self-Powered Ultraviolet-Photodetectors Based on Molecular Beam Epitaxy-Grown AlGaN Quantum-Disks Nanowires (AM4Q.5)
Presenter: Chen Huang, Univ of Science and Technology of China

We have fabricated the novel ultraviolet-photodetectors using AlGaN quantum-disks nanowires. The device responses to 254 nm light sensitively and exhibits a high on/off ratio, a large responsivity, and a fast recovery speed under 0 V.

  Paper

Recent Progress of High-Efficiency AlGaN Deep-UV LED (AM4Q.6)
Presenter: Hideki Hirayama, RIKEN

High-efficiency AlGaN-based deep-ultraviolet light-emitting diodes (deep-UV LEDs) are demonstrated by enhancing light-extraction effiiency (LEE). The external quantum efficiency (EQE) reached to 20.3% by introducing transparent p-type AlGaN contact layer and highly reflective electrode.
