Quantitative comparison of ultracentrifuged and diluted single walled nanotube
(2009)
We have carried out a quantitative comparison of the dispersion quality for ultracentrifuged and diluted surfactant-stabilised single walled nanotube dispersions. We have characterised these dispersions at a set concentration ...
Giant tunneling magnetoresistance with electron beam evaporated MgO barrier and CoFeB electrodes
(2010)
Electron-beam (EB) evaporated MgO grows with (001) texture on amorphous CoFeB when the deposition rate is kept below 5 pm/s. Magnetic tunnel junctions (MTJs) fabricated using this method exhibit similar to 240% magnetoresistance ...

Time-dependent electron transport through a strongly correlated quantum dot: multiple-probe open-boundary conditions approach
(2013)
We present a time-dependent study of electron transport through a strongly correlated quantum dot. The time-dependent current is obtained with the multiple-probe battery method, while adiabatic lattice density functional ...
Influence of electromigration field on the step bunching process on Si(111)
(2010)
We managed to isolate the effects of electromigration in the dynamics of the step bunching process on the vicinal Si(111) surface. Unlike in conventional experiments, we conducted the annealing of Si(111) in a specially ...
Spin transport properties of single metallocene molecules attached to single-walled carbon nanotubes via nickel adatoms
(2011)
The spin-dependent transportproperties of single ferrocene, cobaltocene, and nickelocene molecules attached to the sidewall of a (4,4) armchair single-walled carbon nanotube via a Ni adatom are investigated by using a ...
