Conventional Sm–Co-based alloys have low glass forming ability, and thus are difficult to quench to nanocrystalline structure by rapid solidification. In this paper, nanocrystalline [Sm, rare earth (RE)] Co6.4Si0.3Zr0.3C0.2 (RE = Ce, Sm, Gd, Ho, and Er) alloys have been obtained by melt spinning after compositional modification, as prepared alloys have a microstructure consisting of TbCu7-type SmCo...
With continuous scaling of Complementary Metal Oxide Semicondutor (CMOS) device dimensions, traditional inter-level dielectrics have be replaced by low-k materials, because of the advantages of ultra low-k material such as lower parasitic capacitance, lower cross talk effects, and lower RC delay. The new material in integrated circuits (IC) makes physical failure analysis (PFA) more challenging. This...
Achromatic laser-beam shapers employing spatially varying twisted nematic liquid crystals (LC's) have been demonstrated for high-peak-power applications. The LC molecular orientation was achieved through photolithographic patterning of an alignment layer using polarized UV light.
