This work presents multilayer notch filters prepared by electron beam evaporation. The residual stress in notch filters were predicted and measured. The experimental results show that the transmittance meets the requirements, and the difference between the predicted stress value and the measured stress value is about 28 MPa.

 

This work presents the warpage and residual stress in multilayer films coated on the 8-inch silicon wafers. We use the structured-light illumination, fringe reflection technique, and sub-aperture stitching method to measure surface warpage and radius of curvature for wafers. The residual stress in multilayer thin films .

 

The (Nb2O5/SiO2)4 multi-layer film was deposited by E-gun with ion-beam assisted (IAD) on PET substrate. Residual stress was simulated by finite element method and measured by moiré interferometer. The residual stress was compressive and shearing stress was tensor, and the error of finite element simulated was less than 2%.

 

In this report, we investigated and reported a thermally crosslinkable 9,9-Bis[4-[(4-ethenylphenyl)methoxy]phenyl]-N2,N7-di-1-naphthalenyl-N2,N7-diphenyl-9H-fluorene-2,7-diamine (VB-FNPD) film used as the hole transporting layer of perovskite CsPbBr3 quantum-dot light-emitting diodes. And it show pretty good performance.

 

Here propose a method to grow an inorganic perovskite CsPbBr3 thin film on P-GaN substrate by low pressure chemical vapor deposition (LPCVD). We optimized the growth parameters by optical property of radiative. We achieve the preliminary perovskites LED structure with growing perovskite by LPCVD, ZnO layer and silver contact.

 

This research successfully developed a real-time image recognition method to count the number of birds and drive birds off, including a laser source, an algorithm for image recognition, motor control units, and solar-charged devices. The image recognition algorithm successfully counts the high-speed moving object on CCDs.

 

Diamond-Like Carbon film applied to anti-reflection film under 450 W radio-frequency power and 800W microwave power was used to coat the diamond-like carbon film for 90 minutes. The infrared transmittance in the 3~5μm band can reach 71.18%, and the hardness can reach 5.27 GPa.

 

This paper used silver power mixed with photosensitive resin and applied two photo-polymerization configurations to the 3D printing. By changing different parameters, the printing resolution and solidification could be compared It was verified that the feasibility of producing conductive components using the technology of photo-polymerization additive manufacturing.
