Значения термина polycrystalline на английском

The dc and ac magnetic and EPR studies of polycrystalline samples have been performed.

The polycrystalline material represents the family structure and is characterized by a purely random stacking of layers.

Grain boundaries in the polycrystalline graphene were also visualized reflecting their higher chemical reactivity than the basal plane.

China responded with its own 57 percent duties against U.S. producers of polycrystalline silicon, the raw material for photovoltaic cells.

The wall structure is polycrystalline, with grains in the size range of 7 to 10 nm.

Moreover, the weak coupling across grain boundaries makes transport current densities in untextured polycrystalline samples low and strongly sensitive to magnetic field.

These were fragments of polycrystalline silicon, a highly purified form of silicon that is the bedrock for semiconductor devices and solar cells.

Its products are mainly used in the production of polycrystalline silicon ingots, monocrystalline silicon rods, solar grade silicon and solar cells, among others.

The comparison to the polycrystalline spectra has been made and assignment of all observed modes to the respective vibrations and their symmetry has been proposed.

The samples were characterized by powder- and single-crystal X-ray diffraction, which revealed orthorhombic symmetry for the polycrystalline material and monoclinic symmetry for the single crystals.

Axial and radial polycrystalline (diamond anvil cell) x-ray diffraction measurements reveal a splitting of diffraction lines accompanied by changes in sample texture and elastic anisotropy.
