Oxidation of Tantalum Nano-Film by Microwave Exposure
Massimiliano Zamengo, Lina Grineviciute, Hsin-Hui Huang +4
Oxidation and ablation of 200 nm tantalum films were carried out by three routes: (i) femtosecond (fs-)laser direct write, (ii) high-temperature annealing (HTA) in a tube furnace,…
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.…
Olivine annealed up to 1500 C: changes traced by polarised IR reflectance and magnetization
Daniel Smith, Donatas Narbutis, Hsin-Hui Huang +14
Spectral analysis at the infrared (IR) spectral range is introduced with assignment of synthetic red-green-blue (RGB) colours defined by adjustable wavelength and bandwidth. The RG…
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/…
High Entropy Alloy under Shock Compression: Optical-Pump X-Ray-Probe
Hsin Hui Huang, Meguya Ryu, Shuji Kamegaki +23
High entropy alloys (HEAs) are multi-principal-element alloys designed for tailorable mechanical performance and have been attracting significant engineering interest, yet their fu…
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…
Burst-mode fs-laser direct writing for full-thickness oxidation of Ta thin films
Lina Grineviciute, Hsin-Hui Huang, Haoran Mu +5
Direct fs-laser (1030~nm/200~fs) write of a throughout oxide TaO on a 200~nm Ta film was achieved using a combined ps- and ns- burst mode (Burst-in-Burst or BiB) of fs-…
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…
Anisotropy analysis of bamboo and tooth using 4-angle polarization micro-spectroscopy
Meguya Ryu, Hsin-Hui Huang, Jitraporn Vongsvivut +6
To investigate the anisotropic properties of biomaterials, two distinct classes are considered: polymer-based (e.g., cellulose in plants) and crystalline-based (e.g., enamel in tee…
