This study presents a non-contact thin-film stress measurement system. A fringe reflectometry combined with fast Fourier transform method was used to measure the 3-D surface profile and residual stress of SiO2 thin film deposited on 4-inch silicon wafers.

 

Large-area tandem amorphous/microcrystalline silicon thin-film solar modules are commercially developed and manufactured. Key technologies are introduced into Auria’s 60MW production line. These include special passivation, large-area uniformity, front reflective layers, segment, transverse, and 4-step laser scribing. As a result, low-voltage, see-through, light-through, and color modules are successfully commercialized and installed.

 

In this work, one-turn silver nanohelix array was deposited with glancing angle deposition and substrate cooling technique. By controlling the deposition conditions, the pitch lengths of silver nanohelix arrays were reduced to be less than 180nm.

 

In this work, two titanium nitride nanorod arrays were prepared in a magnetron sputtering system with and without substrate heating. The morphology change due to the substrate heating was also reported here. The signals of surface-enhanced Raman scattering (SERS) from the two TiN nanorod array were compared, measured and analyzed.

 

A deformation-color multi-responsive actuator whose response is controlled by delicate light to mimic the adaptive functions is revealed here. This soft smart material is developed by well-aligned cholesteric liquid crystal polymers (CLCP). It performs a 185 nm wavelength shift of selective reflection and is switched by reacting to exposure time.

 

TiN were grown on smooth substrates using glancing angle deposition technique. Two flow rates of nitrogen were adopted to grow TiN nanorod arrays with different morphologies. Both p-polarized and s-polarized reflectance and transmittance spectra of the TiN nanorod arrays were measured to analyze the longitudinal and transverse plasmonic resonances.

 

We report a new type of dielectric composites obtained through the addition of stress-sensitive nanostructures into polymeric matrixes for highly sensitive pressure sensing. Primary results show that an ultralight load of only 10 mg (~1.0 Pa) can be clearly recognized, which are comparable with most high performance polymer-based pressure sensors.
