Structural colors have shown great promise as an alternative for the existing colorant-based pigments owing to their noticeable advantages, such as high brightness, durability and stability, and environmental safety. They may find potential applications in energy-efficient displays, high-resolution imaging, special effect coatings, and building-integrated photovoltaics.

 

An organic multilayer gas barrier film was prepared by RF magnetron-assisted chemical vapor deposition. A calcium test method was established to measure the limit of water vapor transmission rate (WVTR). By modulating the layer stack design, an effective organic multilayer gas barrier film can be obtained.

 

The diamond-like carbon film was deposited by microwave plasma chemical vapor deposition method with radio-frequency negative bias. Increasing the microwave power, the intensity ratio of I(D)/I(G) of the diamond-like carbon film can be reduced from 0.5227 to 0.4333, which increases the sp3 ratio of the diamond-like carbon film.

 

We first proved experimentally that the direction of hot electrons is highly related to the polarization of the incident light under magnetic fields. By combining the electrical, magnetic, and optical effects of hot electrons, this study is the first to modulate the efficiency of Si-based photodetectors working at telecommunication wavelengths.

 

Group-IV elemental 2D material germanene is grown on MoS2 surfaces by using thermal evaporation. The well stacking germanene on MoS2 surfaces demonstrates the preferential formation of 2D structures on the other 2D material surfaces and the less dependence on the substrate lattice constant of van der Waals epitaxy.

 

We use a laser engraving technique to replace a traditionally roller-based rubbing machine for more complicate liquid crystal alignment. The radial liquid crystal alignment is considered in this paper and the deformation of a light-induced liquid crystal elastomer with such the alignment is investigated.
