Structural and Optoelectronic Behaviour of Copper Doped Cs2AgInCl6 Double Perovskite: A DFT Investigation
I. B. Ogunniranye, T. Atsue, O. E. Oyewande
Recently, direct bandgap double perovskites are becoming more popular among photovoltaic research community owing to their potential to address issues of lead (Pb) toxicity and str…
Theory of off-normal incidence ion sputtering of surfaces of type A_xB_{1-x} and a conformal map method for stochastic continuum models
Oluwole Oyewande, Boluwatife Adeoti
Bradley et. al. recently provided an explanation of nanodot and defect-free ordered ripple production from binary compounds, for normal and oblique incidence ion sputtering respect…
Modeling rough surfaces with Lorentz equations
R. O. Akande, O. E. Oyewande
Surfaces sputtered by ion beam bombardment have been known to exhibit patterns whose behavior is modeled with stochastic partial differential equations. However, we apply a new app…
Discretisation of a stochastic continuum equation of ion-sputtered surfaces
Oluwole Emmanuel Oyewande
The generalised continuum theory model of the dynamical evolution of surfaces sputtered by ion-bombardment is a noisy Kuramoto-Sivashinsky type partial differential equation. For s…
Additional scaling regions of ion-sputtered surfaces
Oluwole Emmanuel Oyewande
In the continuum theory the time evolution of surfaces eroded by ion bombardment is modelled by stochastic partial differential equations (SPDEs). These determine the scaling regim…
Phase boundaries of nanodots and nanoripples over a range of collision cascades
Oluwole Emmanuel Oyewande
One of the open problems of the formation and evolution of the nanostructures on solid surfaces that are driven by particle irradiation is whether all the nano-patterns can be acco…
