Porous silicon templates for electrodeposition of nanostructures

Dielectric relaxation in nanopillar NiFe–silicon structures in high magnetic fields

“…1 shows a scanning electron microscope(SEM) image of the structure and morphology of the nanostructured Si template. [1] Parameters associated with these materials include the electrical transport gap of 0.153eV, which makes the dc conductivity difficult to measure below about 50 K. The NiFe ratio is 81:19, i.e. permalloy.…”

“…[7][8][9] The nanoporous silicon was prepared by electrochemical etching of silicon substrate in a sulphate based electroplating bath [1]. The target pore diameter was controlled by resistance of template and the length of nanopores by changing of the etching time.…”

“…Whenever the system in the insulating state exhibits a dipolar structure it is possible to find dielectric relaxation in some range of temperature and frequency due to the resonance condition ln(f)~1/T. In the present work we have been exploring the dielectric relaxation of NiFe nanowires electrodeposited in nanoporous silicon templates [1] as shown in Fig. 1.…”

Thermal Properties of Porous Silicon

“…The open porous structure and the very large specific surface area of PSi have motivated scientists to introduce different materials into the pores, forming composite structures devoted to different applications relying on the luminescence properties (Bsiesy et al 1995;Herino 1997), electrophysical and magnetic properties of formed heterostructures (Aravamudhan et al 2007), or the sensing capability of the resulting nanostructures (Herino 2000). As it is known, nanocomposites offer a broad avenue of new and interesting properties depending on the kind of involved materials as well as on their morphology (Lai and Riley 2008).…”

Photocurrent Generation of Poly(3,4-ethylenedioxythiophene)-on-TiO2Nanoparticle

“…Recently, attempts have been made to enhance conductivity and photoconducting properties of conductive polymers by control in nanoscale [5][6][7][8][9][10][11].…”
