A single crystal of the title compound, the ternary silicide digadolinium trirhenium penta-silicide, Gd2Re3Si5, was isolated from an alloy of nominal composition Gd20Re30Si50 synthesized by arc melting and investigated by X-ray single-crystal diffraction. Its crystal structure belongs to the U2Mn3Si5 structure type. All atoms in the asymmetric lie on special positions. The Gd site has site symm...

Since the introduction of SiO2/Si devices in the 1960s, the only basic change in the design of a MOSFET has been in the gate length. The channel thickness has fundamentally remained unchanged, as the inversion layer in a silicon MOSFET is still about 10 nm thick. Bipolar transistor base widths have been of sub-micron dimensions all this time. It is time for a new property to be exploited in con...

Silicide-based thermoelectrics are examples of cost-efficient and environmentally friendly new energy materials, which can be used for power-generation applications in the range of 500–800 K. We review the research focusing on the exploration of n-typeMg2IV-based solid solutions (IV= Si, Ge and Sn) and summarize the most prominent discoveries achieved so far in their studies. Owing to their sup...

The intermetallic FeSi exhibits an unusual temperature dependence in its electronic and magnetic degrees of freedom, epitomized by the cross-over from a low-temperature nonmagnetic semiconductor to a high-temperature paramagnetic metal with a Curie-Weiss-like susceptibility. Many proposals for this unconventional behavior have been advanced, yet a consensus remains elusive. Using realistic many...

The formation of ohmic contacts by laser annealing approach is great importance for SiC power devices, since it allows their fabrication on thin substrates, that crucial significance to reduce dissipation. Ni silicide reaction under UV irradiation has been studied in detail with particular focus single pulse approach, order describe the early stage process. use a multi silicide-based means exci...

Using ab initio calculations, we describe how the smallest silicon nanotubes of (2,2) and (3,0) chiral symmetries are stabilized by the axially placed metal atoms, to form nearly one-dimensional structures with substantial cohesive energy, mechanical stiffness, and metallic density of electronic states. Their further reconstructions lead to thicker and shorter wires, while relative stability ca...
