Simultaneous Growth of α-Si3N4 and β-SiC Nanorods

Single-crystalline δ-Ni2Si nanowires with excellent physical properties

“…HRTEM image (Figure 3b) shows the NW of [010] growth direction with 2-nm-thick native oxide. FFT diffraction pattern of the lattice-resolved image is shown in the inset of Figure 3b, which represents the reciprocal lattice planes with [1] zone axis. The phase of the NW has been identified to be δ-Ni 2 Si, constructed with the orthorhombic structure by lattice parameters of a = 0.706 nm, b = 0.5 nm, and c =0.373 nm.…”

“…One-dimensional materials, such as nanorods, nanotubes, nanowires (NWs), and nanobelts, are promising to be utilized in spintronics, thermoelectric and electronic devices, etc. [1-5]. Metal silicides have been widely synthesized and utilized in the contemporary metal-oxide-semiconductor field-effect transistor as source/drain contact materials, interconnection [6], and Schottky barrier contacts.…”

Low-temperature preparation of silicon nitride via chemical metathesis route

“…Up to now, several methods have been proposed to synthesize silicon nitride such as direct nitridation of silicon [5,6], ammonolysis (gas phase) of silicon tetrachloride [7][8][9], carbothermal reduction of silicon dioxide [10][11][12], vapor-solid (VS) thermal reaction [13]. All these methods are either time consuming or requiring high temperature (N1300 8C).…”

Comparison of Silicon Nitride Nanofibers Synthesized Using Silica Nanopowders and Silica Gel

“…In particular, the fabrication of one dimensional nanowires, nanorods, and nanofibers of ceramics such as silicon nitride has been investigated intensively [5][6][7][8][9][10][11][12][13][14][15][16]. Silicon nitride has many attractive properties including high strength, hardness, and resistance to thermal shock and oxidation.…”

“…Diatomite, used as the source of silica, and carbon black mixtures were subjected to the carbothermal reduction process in an atmosphere of nitrogen, thereby producing both alpha and beta silicon nitride fibrous products. Wu et al [10] produced silicon nitride and silicon carbide nanorods by calcining pellets of silica nanoparticles with active carbon at 1450˚C in a flowing nitrogen atmosphere.…”
