Defect-induced Fermi level pinning and suppression of ambipolar behaviour in graphene
Zakaria Moktadir, Shuojin Hang, Hiroshi Mizuta
We report on systematic study of electronic transport in low-biased, disordered graphene nanowires. We reveal the emergence of unipolar transport as the defect concentration increa…
A U-shaped bilayer graphene channel transistor with a very high Ion/Ioff ratio
Z. Moktadir, S. A. Boden, A. Ghiass +2
A novel graphene transistor architecture is reported. The transistor has a U-shape geometry and was fabricated using a gallium focused ion beam (FIB). The channel conductance was t…
Epitaxial growth under oblique incidence
Z. Moktadir
A continuum one dimensional model of homoepitaxial growth under oblique incidence is investigated. We carried out numerical integration of a continuum equation incorporating a shad…
Fabrication of Magneto-Optical Atom Traps on a Chip
G. Lewis, Z. Moktadir, C. Gollasch +7
Ultra-cold atoms can be manipulated using microfabricated devices known as atom chips. These have significant potential for applications in sensing, metrology and quantum informati…
Scale decomposition of molecular beam epitaxy
Z. Moktadir
In this work, a study of epitaxial growth was carried out by means of wavelets formalism. We showed the existence of a dynamic scaling form in wavelet discriminated linear MBE equa…
Scaling properties of pyrex and silicon surfaces blasted with sharp particles
Z. Moktadir, H. Wensink, M. Kraft
The blasting of brittle materials with sharp particles is an important fabrication technology in many industrial processes. In particular, for micro-systems, it allows the producti…
