Charging/discharging of Au (core)/silica (shell) nanoparticles as revealed by XPS
(American Chemical Society, 2005)By recording XPS spectra while applying external voltage stress to the sample rod, we can control the extent of charging developed on core-shell-type gold nanoparticles deposited on a copper substrate, in both steady-state ... -
Comparison of two methods of surface profile extraction from multiple ultrasonic range measurements
(Institute of Physics Publishing, 2000)Two novel methods for surface profile extraction based on multiple ultrasonic range measurements are described and compared. One of the methods employs morphological processing techniques, whereas the other employs a spatial ... -
Differentiation of domains in composite surface structures by charge-contrast x-ray photoelectron spectroscopy
(2007)An external bias is applied to two samples containing composite surface structures, while recording an XPS spectrum. Altering the polarity of the bias affects the extent of differential charging in domains that are chemically ... -
Dilbilimsel bir yaklaşım denemesi: Tekirdağ yöresinden bir ninni
(Geleneksel Yayıncılık, 2010)Dilbilimsel kuram edebiyatta genellikle şiir incelemelerinde kullanılan bir yöntemdir. Biçimsel nitelikleri yönünden şiiri andıran ninnileri de bu kuram dâhilinde ele almak mümkündür. Bu çalışmada ninni türünün bir örneği, ... -
Morphological surface profile extraction with multiple range sensors
(Elsevier, 2001)A novel method is described for surface pro"le extraction based on morphological processing of multiple range sensor data. The approach taken is extremely #exible and robust, in addition to being simple and straightforward. ... -
Preparation, surface state and band structure studies of SrTi (1-X)Fe (x)O (3-δ) (x = 0-1) perovskite-type nano structure by X-ray and ultraviolet photoelectron spectroscopy
(2012)In this report, SrTi (1 - x)Fe (x)O (3 - δ) photocatalyst powder was synthesized by a high temperature solid state reaction method. The morphology, crystalline structures of obtained samples, was characterized by X-ray ... -
Surface wave splitter based on metallic gratings with sub-wavelength aperture
(Optical Society of American (OSA), 2008)We investigated the splitting of surface electromagnetic waves trapped at the output surface of a one-dimensional metallic grating structure. The output gratings of the structure asymmetrically such that the output surfaces ... -
Transient surface photovoltage in n-and p-GaN as probed by x-ray photoelectron spectroscopy
(2011)Transient surface photovoltage (SPV) of n and p-GaN was measured using x-ray photoelectron spectroscopy (XPS) with a time resolution of 0.1 s. The measured SPV transients for both n- and p-GaN are 0.1 s, and for the n-GaN ... -
Two-dimensional x-ray photoelectron spectroscopy for composite surface analysis
(2008)We describe a method for obtaining two-dimensional X-ray photoelectron spectroscopic data derived from the frequency dependence of the XPS peaks recorded under electrical square-wave pulses, which control and affect the ... -
XPS analysis with pulsed voltage stimuli
(2006)We record XPS spectra while applying 0 to +10 V or 0 to -10 V square pulses to the sample rod, which normally results in twinning of all peaks at correspondingly increased (for +10 V) or decreased (for -10 V) binding ...
