Recently, a new process to manufacture vertical RESURF devices was proposed. By using trench etching and subsequent vapor phase doping the alternating p–n junctions in the drift region of such a diode can be formed. For the characterization of thes

We have prepared face centered close packed arrays of polystyrene spheres using convective self-assembly. The optical properties of the arrays of spheres were studied and revealed high quality crystals that could be prepared using this method. Optica

Thermoplastic vulcanizates (TPVs), as prepared by dynamic vulcanization, are blends in which cross-linked rubber particles are finely dispersed in a thermoplastic matrix. The reported nylon-6/EPDM TPVs show significant strain recovery behavior, even

The frequency dependence of the nonlinear dielectric increment was studied for benzene solutions of 4,4′-n-hexylcyanobiphenyl (6CB), 4-(trans-4′-n-hexylcyclohexyl)-isothiocyanatobenzene (6CHBT) and 1-[3-n-decylbiphenyl]-2-[4-isothiocyanatophenyl]

We study second-order nonlinear optical properties of Langmuir–Blodgett films of two chiral helicenebisquinones. We compare the second harmonic efficiency of both materials and we demonstrate that the second harmonic signal generated by a Langmuir

The microstructure of (0 0 1)-oriented epitaxial CeO2 thin layers grown on R-plane sapphire (Al2O3) by off-axis RF sputtering was investigated. The crystalline perfection of CeO2 layers was characterized by Bragg–Brentano X-ray spectra, rocking cur

In this Letter we describe the effect of heating on the quality, morphology and nonlinear optical efficiency of anisotropic Langmuir–Blodgett films composed of a chiral helicenebisquinone derivative. The samples were studied with second harmonic ge
