Er ions were implanted into n-type 4H-silicon carbide (SiC) materials, which are useful host materials because they provide a wide band gap and improve the luminescence properties of Er 3+ ions.
Introduction An erbium (Er)-doped semiconductor is a useful material for light-emitting devices in optical communication systems, since the intra-4f-shell transitions of Er ions cause sharp and temperature-stable luminescence in various host materials [1],[2] at the wavelength of 1.54 μm, which corresponds to the minimum absorption of silica-based optical fibers.
We used n-type 4H-SiC as host materials.
The projected range (Rp) and straggling (ΔRp) were Journal Title and Volume Number (to be inserted by the publisher) 2 505.1 and 78.8nm, respectively.

However, it is necessary to simplify the physical model due to the following reasons: First, gypsum is commonly used as a simulating material, it is difficult to accommodate the density proportional compatibility of materials; Second, it is not easy to simulate the temperature field in such a way that to be analogous to the real environment.
Parameters Parameters for dam and foundation materials: Dam concrete: Elastic modulus E=2.0 GPa; Poisson ratio n=0.167; density r=2400 kg/m3 To simplify the procedure of computation but not impact on the significance of the study result, see the dam foundation is homogeneous.

T2 means the knowledge transfer from suppliers to manufacturers, including the supplier's inventory, raw materials, a variety of performance indicators, using parameters, alternative raw materials, and new materials selection and so on.
T2′ means the knowledge transfer from manufacturers to suppliers, including production planning, procurement planning, production technology, raw materials problem.
Successful knowledge transfer between suppliers and manufacturers will not only help suppliers to lower inventory, improve the technical specifications of raw materials; but also help manufacturers to reduce procurement costs and production costs, enhance the quality of products.
