Fabrication of high quality InP nanopillar structures, with the help of self-masking properties and using the electron cyclotron resonance ion etching techniques, can be a easy demanding and one step large scale production method compared to the trad

We investigated the reversal mechanism in a Co/CoO exchange bias bilayer with a pronounced magnetocrystalline anisotropy in the ferromagnet. The anisotropy, which is induced by the growth of a highly textured Co layer, imposes a distinct reversal mec

Here we study the pattern formation on tantalum foils after low-energy ion irradiation with 3 keV Ar ion beams. Surfaces display a variety of patterns decorated with nanodots. The associated surface roughness demonstrates an initial increase but a su

Formation of self-organized Ta nano-structures by argon ion sputtering of Ta foil: XPS and AFM study
Publikováno v:
Journal of Electron Spectroscopy and Related Phenomena. 180:1-5
The nano-structured Ta has been prepared by 3 keV argon ion sputtering of the Ta foil. The XPS and AFM studies were carried out on samples sputtered for fluences ranging from 6.0 × 1 0 15 to 3.6 × 1 0 16 ions/cm2. The sample sputtered at lowest flu

Size dependant core-level shifts have been investigated here for the InP nano-dots fabricated by the 3 keV ion irradiation. The self assembled nano dots exhibit core-level shifts and band gap expansion. The core-level shifts are however inhomogeneous

We report formation of self organized InP nano dots using 3 keV Ar+ ion sputtering, at 15° incidence from surface normal, on InP(111) surface. Morphology and optical properties of the sputtered surface, as a function of sputtering time, have been in

The scaling parameters have been studied here for InP(111) surfaces that evolve after implantation with MeV ions. The surfaces show the development of nano pattern and kinetic roughening. Growth exponent β, roughening exponent and the characteristic

We report the physical and electronic properties of BP films of 1:1, 1:1.15 and 1.25:1 stoichiometry prepared by co-evaporating B and P onto glass and Si (100) substrates. Compositional information was obtained from X-ray photoelectron spectroscopy m

Temporal evolution of nano dots fabricated, in off-normal geometry but in the absence of rotation, on InP(1 1 1) surfaces by 3 keV Ar ion sputtering is reported here. After 10 min of sputtering, self-assembled nano dots with mean diameter of 24 ± 4
