We report the first determination of the slip coefficient for tubular carbon structures that have been produced by chemical vapor deposition on a porous alumina substrate with nominal pore diameters of 200 nm. A uniform 20−30 nm thick carbonaceous coating was formed over the pores. The permeability of the porous alumina was then measured using a pressure/flow apparatus. A finite element code with adjustable slip boundary conditions was used to model transport through the alumina. In the absence of a carbonaceous material, transport was well described by diffuse reflection at the wall. When a carbon nanotubule was present, however, a tangential-momentum accommodation coefficient, σ v , of 0.52 ± 0.1 was predicted for argon, nitrogen, and oxygen.

“…Recent advances in the technology of fabrication of quasi-2D, -1D, -0D nanocrystals have stimulated the theoreticians' interest in formulating models describing physical phenomena associated with nanocrystals [1][2][3][4][5][6][7][8][9][10][11][12]. These structures are attractive both for scientific investigation and for the development of a new generation of electronic devices.…”

“…Nowadays not only perfect planar multilayer structures but also cylindrical and spherical structures are being intensively investigated [7][8][9][10][11][12][13]. Polaron energy is evaluated in [13][14][15] using perturbation theory, in [16] using the weak coupling approximation, in [17] using the dielectric continuum model and in [18] using the Feynman variational principle.…”

Polaron states in cylindrical and spherical quantum dots with parabolic confinement potentials are investigated applying the Feynman variational principle. It is observed that for both kinds of quantum dots the polaron energy and mass increase with the increase of Fröhlich electron-phonon coupling constant and confinement frequency. In the case of a spherical quantum dot, the polaron energy for the strong coupling is found to be greater than that of a cylindrical quantum dot. The energy and mass are found to be monotonically increasing functions of the coupling constant and the confinement frequency.

During the last decade, photonic crystals, also known as photonic microstructures or photonic bandgap structures, have matured from an intellectual curiosity concerning electromagnetic waves to a "eld with real applications in both the microwave and optical regime. In this review, we shall focus on progress and the prospects for semiconductor structures that mainly involve guided modes interacting with periodic structures, but we also evaluate alternative material systems and fabrication methods, e.g. those based on self-organisation. We shall go from basic concepts, via a discussion of the state of the art, to device applications. Naturally, the discussion of the applications will be more speculative, but we attempt to evaluate the real prospects o!ered by photonic crystals at optical frequencies while considering practical limitations. In doing so, we identify a variety of areas such as the combination of quantum dot light emitters with photonic crystals that seem particularly promising. We discuss the prospects for enhanced light}matter interactions in photonic crystals and the related material and design issues. Overall, the aim of this review is to introduce the reader to the concepts of photonic crystals, describe the state of the art and attempt to answer the question of what uses these peculiar structures may have.
