Detection of Optical Sensing Arrays Using White Light Fourier Transform Spectrometer and Commercial spectrometer
A white light Fourier transform spectrometer (WLFTS) was built based on a Michelson interferometer to detect a plasmonic biosensor with large-area gold nanoslit array structures. Transmission spectra were measured simultaneously with both WLFTS and a commercialized spectrometer for comparison. Detection under various refractive index liquids and protein-binding are demonstrated.

The effect of de-molding temperature and pillar diameter on stretched polycarbonate nanopillars by nanoimprint
In this study, we used a simple method to fabricate high aspect ratio polymer nanohairs on polycarbonate substrate by nanoimprint. The height of the stretched nanopillars was influenced by the de-molding temperature and the original pillar diameter. The height of the PC nanopillars can be stretched to twice of their original size.

Characteristics of strain-induced broadband absorption in MoS2-based photodetector via patterned sapphire substrate
We demonstrate the photodetector by growing two dimension transition metal dichalcogenides (bilayer MoS2) on patterned sapphire substrate. The different stains will cause peak shift in Raman and PL spectra, which can enhance the ability of electron collecting and provide broadband absorption. These characteristics make it become attractive for photodetector application.

Enhanced optoelectronic properties of Al doped ZnO layers by formation of CuO nano-wire structures
In this study, the structure and optoelectronic properties of the finished AZO/CuO nano-wires/AZO thin film are studied. Structural characterization by high-resolution transmission electron microscopy (HRTEM) indicates that the CuO nano-wires are mainly single crystal phases. The optimum density for the CuO nano-wire structures is achieved by sputtering a 6 nm Cu thickness. This gives the lowest resistance of 1.4 × 10-4 Ω-cm and the average transmittance from 400-800nm is about 84%. The best figure of merit for the AZO/CuO nano- wires/AZO layer is 1.54×10-2 (Ω-1), which shows that the application of AZO on transparent conductive electrode is viable.

We report a method to stabilize blue phase liquid crystals (BPLCs) by photo-polymerizing the doped chiral polymers at isotropic phase, indicating that no branched structures cross the LC bulk will be generated. The chiral polymers not only control the pitch length by light-illumination, but broaden the temperature range of BP-LCs.

Enhanced optoelectronic properties on Al–doped ZnO layers by leading nano-Ag particles on the textured seed layer
In this study, the textured surface of AZO is treated as a seed layer, which is expected to lead the uniform distribution of nano-Ag particles to deposit on the surface. Finally, the AZO(20nm)/nano-Ag/AZO(20nm) ultra-thin film had been grown as transparent conductive film. The results show that the resistance of ultra-thin film reduces to 4.67×10-5 Ω-cm and the average transmittance in the visible range increases to 88.7 %. The best figure of merit for the ultra-thin film is 2.84×10-2 Ω-1, which promote the application of AZO on transparent conductive thin film.

Oxidized nanoporous silicon (ONPS) thin films that were prepared by electrochemical etching of p+-Si substrates and a followed rapid-thermal-oxidation treatment exhibited largely enhanced ultra-violet (UV) photoresponses. The improved UV-sensing properties are attributed to the uniformly distributed nanoparticles embedded in the ONPS films, which are supposed to be with silicon-core/oxide-shell nano-structures.

Fabrication and sulfurization of Cu2SnS3 thin films by reaction rate tuning the concentration of Cu-Sn-S precursor ink.
This paper reports a polyetheramine-based method, which can be controlled by varying the concentration of solution for the preparation of Cu-Sn-S precursor nanoinks without a second phase for use in sulfurization. As a result, the SnS phase reacted more readily and more rapidly, resulting in the early formation of a stoichiometric CTS thin film during sulfurization.
