Notizen: Abstract The crystal structure of N-(4-nitrophenyl)-N-phenylsulfonamide (C18H14N2O4S), a derivative of sulfonamide, has been determined by X-ray diffraction method using CuKα radiation. The compound crystallizes in the monoclinic space groupP21/n, witha=24.463(1),b=5.745(2),c=11.428(3)Å andβ=94.39(2)°. The structure was solved by direct methods and refined by full-matrix least squares to a finalR value of 0.045 with 3032 unique reflections. The dihedral angle between the substituents phenyl ring B and the phenyl A is 94.7(3)°. The S atom is in the usual distorted tetrahedral configuration.

Notizen: Molecular dynamics simulations of the deposition of atomic H on both c-Si and a-Si:H substrates are performed to understand the physical processes occurring in the presence of an atomic H flux during growth. The absorption probability, and dynamical behavior of the H are studied as a function of the incident H energy. Both hydrogen absorption and backscattering events are observed. The hydrogen reflection probability has a maximum around 50 eV and decreases at higher incident kinetic energies. In the hydrogen backscattering events a substantial subsurface penetration and energy transfer through collisions are observed. Hydrogen absorption events have been closely analyzed and a surface hydrogen release event was observed during an absorption event.

Notizen: An attempt is made to investigate the thermoelectric power of the electrons under strong magnetic quantization in n-channel inversion layers of ternary chalcopyrite semiconductors at low temperatures, taking n-channel inversion layers on CdGeAs2 as examples, under both the weak and strong electric field limits, respectively. We have formulated the magneto-thermo power on the basis of newly derived two-dimensional electron energy spectra for both the limits by considering various types of anisotropies of the band parameters within the frame work of k(large-closed-square)p formalism. It has been observed that, the magneto-thermo power decreases with increasing surface electric field and decreasing quantizing magnetic field in an oscillatory manner for both the limits. The crystal field parameter enhances the numerical magnitudes and the corresponding results for n-channel inversion layers of parabolic semiconductors have also been obtained as special cases from the generalized expressions under certain limiting conditions.
