n this work we simulated the growth of amorphous silicon on a substrate of a two-layer-slab of crystalline silicon with various surface indices. We used the Lennard-Jones form for the pair potentials and the Axilrod-Teller form for the three-body potentials. The growth is realized by means of a continuum Monte-Carlo method and the radial distribution functions are compared for various cases

A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01) The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
THE NONLINEAR COLD PLASMA-BUNCHED BEAM INTERACTION AND THE PLASMA WAKEFIELD ACCELERATOR CASE BILIKMEN, S; NAZIH, RM (IOP Publishing, 1993-02-01) In this paper, a nonlinear analytical solution for a cold plasma-bunched beam system based on the Hamiltonian formalism where alpha = n(b)/n0 and beta(phi) = upsilon(phi)/c have been taken as parameters matching between zero and unity is given. The oscillation limiting energies, frequencies and transformer ratios have been carried out in general for both the one-dimensional and the case where a small transverse component of motion is included. The plasma wakefield accelerator has been treated as a special c...
A 2D Slotted Rod Type PhC Cavity Inertial Sensor Design for Impact Sensing Orsel, Ogulcan Emre; ERDİL, MERTCAN; Kocaman, Serdar (Institute of Electrical and Electronics Engineers (IEEE), 2020-02-01) A tunable 2D rod type Si Photonic Crystal cavity based impact sensing configuration is proposed and numerically analyzed. The cavity is sandwiched by perfect electric conductor (PEC) boundaries in order to provide out-of-plane light confinement. An on-purpose air slot is introduced between the Si rods and top PEC plate moving the light confinement into the slotted region and making the cavity highly responsive to the displacement of top PEC boundary. Optomechanical coupling strength is calculated to be on t...
Transport of neutral atoms in plasma with a source of neutral atoms and molecules Bilikmen, Sinan; Rhimi, Mohamed Nazih (IOP Publishing, 1989-1-1) A model for steady state neutral atom transport in a finite thickness, one dimensional plasma slab with a source of neutrals and molecules at the edge, is formulated. A computer code OMID is developed for computational analysis. The analysis shows that the cold neutral particle density is maximum near the wall, the total fuelling profile peaks in the vicinity of the wall for a molecular source more than for an atomic one, energetic neutrals formed in successive charge exchange collisions carry energy to the...
Synthesis of carbon nanotubes by a plasma based pulsed electron beam generator Goktas, H.; Ayhan, U. B.; Gündüz, Güngör; Disbudak, H.; Eryilmaz, E.; Oke, G.; Cicek, B.; Somer, M. (IOP Publishing, 2006-01-01) Carbon nanotubes (CNTs) were synthesized by using a plasma based electron beam generator, which has a fast filamentary discharge formed from the superposition of an ordinary low-pressure dc glow and a high-current pulsed discharge. To our knowledge, CNTs are synthesized for the first time by this method. Acetylene was used as the carbon source and the iron catalyst coated silica substrates were prepared by the sol-gel technique. The silica plates were first coated with an appropriate iron (III) nitrate solu...
