The polaron effect on the ground-state level of a hydrogenic impurity in a semiconductor quantum well is calculated as a function of the well thickness. The formulation is based on an extension of the strong-coupling polaron theory and covers the overall range of the electron-phonon coupling strength. It is observed that in a GaAs-based quantum structure the phonon-induced shift in the binding energy is smaller than that in the bulk case except for too narrow well sizes.

Slip-flow heat transfer in microtubes with axial conduction and viscous dissipation - An extended Graetz problem Cetin, Barbaros; Güvenç Yazıcıoğlu, Almıla; KAKAÇ, SADIK (Elsevier BV, 2009-09-01) This study is an extension of the Graetz problem to include the rarefaction effect, viscous dissipation term and axial conduction with constant-wall-heat-flux thermal boundary condition. The energy equation is solved analytically by using general eigenfunction expansion. The temperature distribution and the local Nusselt number are determined in terms of confluent hypergeometric functions. The effects of the rarefaction, axial conduction and viscous dissipation on the local Nusselt number are discussed in t...
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 ...
Ion-matrix sheaths related to planar targets with semicylindrical grooves Demokan, O; Filiz, Y (AIP Publishing, 2003-01-01) 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 agreem...
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 ...
