The quantum confined Stark effect (QCSE) in Si nanocrystals embedded in a SiO(2) matrix is demonstrated by photoluminescence (PL) spectroscopy at room and cryogenic temperatures. It is shown that the PL peak position shifts to higher wavelengths with increasing applied electric field, which is expected from carrier polarization within the quantum dots. It is observed that the effect is more pronounced at lower temperatures due to the improved carrier localization at the lowest energy states of the quantum dots. Experimental results are shown to be in good agreement with phenomenological model developed for the QCSE model.

The role of amorphous precursor in phase selection hierarchy in marginal metallic glasses YILDIRIM, CİHAN; KUTSAL, M.; OTT, R. T.; BESSER, M. F.; KRAMER, M. J.; Kalay, Yunus Eren (Elsevier BV, 2016-12-15) The solid state amorphous structure and devitrification products of Al90Tb10 alloys produced by Cu block meltspinning and magnetron sputtering were investigated by a combined study of differential scanning calorimetry, in-situ X-ray diffraction and conventional transmission electron microscopy. The as-prepared specimens were found to be fully amorphous according to the electron and X-ray diffraction. The thermal analysis and in-situ XRD analyses of the amorphous samples having the same chemistry but differe...
Direct measurement of charge transport through helical poly(ethyl propiolate) nanorods wired into gaps in single walled carbon nanotubes Wang, Nan; Yano, Koji; Durkan, Colm; Plank, Natalie; Welland, Mark E.; Zhang, Yan; Ünalan, Hüsnü Emrah; Mann, Mark; Amaratunga, G. A. J.; Milne, William I. (IOP Publishing, 2009-03-11) We report the direct measurement of electrical transport through rod-like polymer molecules, of poly(ethyl propiolate) (PEP), utilizing single walled carbon nanotubes (SWNTs) as electrodes. The electrical properties of the devices were measured (i) before cutting a SWNT, (ii) when a SWNT was cut and (iii) after PEP deposition into the nanoscale gap in a cut SWNT. The gate-dependent electrical properties showed a reduction in current from I-on = 2.4 x 10(-7) A for SWNT devices to I-on = 3.6 x 10(-9) A for PE...
Effect of electroless etching parameters on the growth and reflection properties of silicon nanowires Ozdemir, Baris; Kulakci, Mustafa; Turan, Raşit; Ünalan, Hüsnü Emrah (IOP Publishing, 2011-04-15) Vertically aligned silicon nanowire (Si NW) arrays have been fabricated over large areas using an electroless etching (EE) method, which involves etching of silicon wafers in a silver nitrate and hydrofluoric acid based solution. A detailed parametric study determining the relationship between nanowire morphology and time, temperature, solution concentration and starting wafer characteristics (doping type, resistivity, crystallographic orientation) is presented. The as-fabricated Si NW arrays were analyzed ...
The electronic structure of a quantum well under an applied electric field Sari, H; Ergun, Y; Sokmen, I; Tomak, Mehmet (Elsevier BV, 1996-01-01) The effects of an applied electric field on quantum well subband energies are calculated variationally within the effective mass approximation for model potential profiles. The concept of a quasi-bound state is examined critically. For higher electric field values it is shown that the quasi-bound state approximation for the ground and first excited state of the electron, and for the ground state of the hole is valid.

Effect of thermal neutron irradiation on the elastic constants of tourmaline Özkan, H. (Informa UK Limited, 1987-2) The effect of thermal neutron irradiation due to the B10(n, α)Li7 reaction on the elastic wave velocities and the elastic moduli of tourmaline crystals has been studied. Oriented tourmaline samples have been irradiated with thermal neutrons to 7.6 × 1018n/cm2 and the elastic wave velocities determined by ultrasonic measurements. The elastic wave velocities are not affected by thermal neutron irradiation below 8 × 10l7n/cm2, effects starting to appear at approximately 1 × l018n/cm2 with more important decrea...
