Introduction Since the discovery of conducting polyacetylene by Shirakawa et al. in 1977, electronically conducting polymers have gained much interest in the field of electronic devices due to their intrinsic electrical and physical properties[1].
For instance, the effect of surfactant on the morphology, conductivity, and thermal stability of the chemically synthesized poly(pyrrole) has been reported by Omastova et al[4,5].
Element analysis was tested by Elementar Vairo EL III made in Germany.

The rare-earth (RE) doping of Si and Si-related materials [1-7] in the last years has been extensively studied for the development of light-emitting devices in the Si-based optoelectronics initiated by the reports on the photoluminescence (PL) and electroluminescence (EL) centered at around 1.54 μm of Er3+ (4I13/2→4I15/2) in Si [8].
The He stopping power used here was presented by Chu et al.’s book [10].

Qin et al. [11] have observed the UV emission (3.4−3.6 eV) from oxidized PS at 300 K.
The UV emission from the silicon oxide film prepared by magnetron sputtering was measured by Song et al. [10].

Thus the cohesive zone model (CZM) which has been used by Lin et al. [1] was employed in this paper to analyze the edge crack extension under cold rolling process.

Similar trends of v and w affecting r were found for SLM of Al-10Si-0.3Mg alloy by Aboulkhair et al. [2].
In the study of SLM of the same Al alloy, Read et al. [3] show the trend of decreasing porosity level as E increases, although the scatters associated with the data are generally very high.
