Diamond membranes: platform for photonic and opto-mechanical applications
Hsin-Hui Huang, Gediminas Seniutinas, Haoran Mu +8
Diamond 1 - 10 micrometers thick membranes are platform for photonic, quantum and opto-mechanic devices with applications across UV-IR spectral ranges. IR characterization of diamo…
UV-enhanced SEM: towards orientation and electron work function imaging
Maciej Kretkowski, Haoran Mu, Hsin-Hui Huang +6
Deep-UV ~ 250 nm (4.96 eV) tilted in-situ co-illumination of the sample under imaging by scanning electron microscope (SEM) is developed at a robust and practical instrument level.…
Nanoscale Surface Analysis of High Entropy Alloy
Hsin-Hui Huang, Meguya Ryu, Yoshiaki Nishijima +10
Nanoscale surface analysis of 1 micrometer thick high entropy alloys (HEAs) was carried out using nano-IR for hyperspectral imaging and single point spectroscopy in the 700-1700 1/…
Structure orientation determined in transmission and reflection: q-plate
Hsin-Hui Huang, Meguya Ryu, Shuji Kamegaki +9
Determination of orientation in the imaged sample/scene has a large application potential when the anisotropy of properties is analysed, usually, under a linearly polarised illumin…
Ablation of black-Si by (Gauss-)Bessel femtosecond laser beams
Nan Zheng, Hsin-Hui Huang, Nguyen Hoai An Le +7
Laser machining and modification of black-Si (b-Si) by femtosecond laser Gaussian (G-) and Gauss-Bessel (GB-) beams are compared at a wavelength of 1030 nm. The GB-beam was generat…
Bessel-beam direct-write of the etch-mask in a nano-film of alumina for high-efficiency Si solar cells
Tomas Katkus, Soon Hock Ng, Haoran Mu +14
Large surface area applications such as high-efficiency > 26% solar cells require surface patterning with 1-10 micrometers periodic patterns at high fidelity over 1-10 cm^2 areas (…
