In this work, the ion-matrix sheaths near planar targets with infinitely long, semicylindrical grooves are studied analytically to optimize ion implantation, concerning a broad range of industrial products. The potential profiles inside and outside the groove are derived and the velocity components inside the groove are estimated. The variation of the angle of incidence on the surface of the groove and the constant potential contours outside the groove are obtained. Results are observed to be in good agreement with the numerical simulations. Finally, suggestions for improving the uniformity of implantation on the surfaces of such grooves are stated.

Singularities of spectra of infrared reflection of tertiary compounds of the type T1BX2 Hasanlı, Nızamı; Khomutova, M.D.; Sardarly, R.M.; Tagorov, V.I. (Springer Science and Business Media LLC, 1977-07-01) The frequencies of lattice vibrations are calculated for compounds of the type T1BX2 on the basis of the linear-chain model. The calculated frequencies are compared with experimental values for TlGaS2 and TlGaSe2. The good agreement between the calculated and experimental frequencies serves as proof of the applicability of the linear-chain model to compounds of the T1BX2 type. The proposed method of calculation of frequencies makes it possible to predict the theoretical frequencies of lattice vibrations of ...
Atomic chains and lattice vibration characteristics in A2IIIB3VI compounds with tetrahedral coordination of atoms Hasanlı, Nızamı; Khomutova, M.D. (Springer Science and Business Media LLC, 1977-04-01) On the basis of the presence of atomic chains in A2 IIIB3 VI compounds having zincblende defect structure, a linear-chain model is used to calculate the lattice vibration frequencies. The agreement of the calculated and experimental frequencies is an indication of the applicability of the model and enables one to determine the motion of various atoms during the corresponding vibrations.
Defect-controlled transport properties of metallic atoms along carbon nanotube surfaces Barinov, Alexei; Toffoli, Hande; Fabris, Stefano; Gregoratti, Luca; Aballe, Lucia; Dudin, Pavel; Baroni, Stefano; Kiskinova, Maya (American Physical Society (APS), 2007-07-01) The diffusion mechanism of indium atoms along multiwalled carbon nanotubes is studied by means of photoemission spectromicroscopy and density functional theory calculations. The unusually high activation temperature for diffusion (approximate to 700 K), the complex C 1s and In 3d(5/2) spectra, and the calculated adsorption energies and diffusion barriers suggest that the indium transport is controlled by the concentration of defects in the C network and proceeds via hopping of indium adatoms between C vacan...
Progressive structural and electronic properties of nano-structured carbon atomic chains Usanmaz, D.; Srivastava, G. P. (AIP Publishing, 2013-05-21) Ab initio calculations, based on the planewave pseudopotential method and the density functional theory, have been reported on the changes in the electronic and structural properties of short carbon atomic chains held rigidly between hydrogenated thin armchair graphene nanoribbons (N-a-AGNR) of dimer line numbers N-a = 4 and 5. We have considered chains of several lengths (n = 4-9 atoms) and with different forms of attachment with the AGNRs. It is found that odd-numbered chains are metallic in nature, with ...
Nonlinear mode coupling and sheared flow in a rotating plasma Uzun Kaymak, İlker Ümit; Choi, S.; Clary, M. R.; Ellis, R. F.; Hassam, A. B.; Teodorescu, C. (IOP Publishing, 2009-01-01) Shear flow is expected to stabilize the broad spectrum of interchange modes in rotating plasmas. However, residual fluctuations may still persist. To investigate the presence of such fluctuations, sixteen magnetic pickup coils equally spaced on a crown have been mounted inside the vacuum vessel, at the edge of a rotating plasma in mirror configuration. A comprehensive analysis of the magnetic fluctuations shows that very low spatial mode numbers survive under the imposed shear flow. Nevertheless, temporal F...
