Interference studies in germanium determination by electrothermal atomic absorption spectrometry Anwari, Mohammad Ali; Ataman, Osman Yavuz; Department of Chemistry (1994)
Material characterization with terahertz time-domain spectroscopy Köseoğlu, Devrim; Bilikmen, Kadri Sinan; Department of Physics (2010) Terahertz time-domain spectroscopy systems were developed and used for the anaylsis and characterization of various materials. By using ultra-fast Ti:Sapphire and Er-doped fiber lasers, terahertz time-domain spectrometers of different configurations were constructed and tested. To increase the accuracy and sensitivity of the measurements, the systems were optimized for spectroscopic analysis. MBE grown nominally undoped epitaxial GaAs samples were used for the spectroscopic measurements. These samples were ...
Strain induction on GE nanobeams by electrostatic actuation Ayan, Arman; Yerci, Selçuk; Department of Electrical and Electronics Engineering (2018) Germanium (Ge) is one of the most promising materials to accomplish the monolithic integration of optics and electronics on the same chip, mainly due to its compatibility with the existing silicon (Si) technology, high charge carrier mobility and high absorption coefficient in the near-infrared region. However, realization of efficient Ge light emitters requires techniques such as tensile strain induction, tin (Sn) incorporation and/or heavy n-type doping to alter its band gap enabling direct transitions. A...
Atom trapping vapor generation atomic absorption spectrometry for inorganicarsenic speciation analysis / Njie, Njaw; Ataman, Osman Yavuz; Department of Chemistry (2014) Speciation analysis is important for arsenic. Novel methods to improve the sensitivity for determination of total arsenic and arsenic speciation have been developed. The techniques basically rely on generation of volatile arsenic species by reaction with sodium borohydride followed by trapping on a W-coil atomizer and finally releasing analyte atoms by heating the atomizer; the system is named as W-coil atom trapping electrothermal atomic absorption spectrometry (WC-ETAAS). Sample solution may be introduced...
Hydride generation and preconcentration of bismuth on a single-drop followed by determination using electrothermal atomic absorption spectrometry Dügencili, Başak; Ataman, Osman Yavuz; Department of Chemistry (2015) A novel method for determination of bismuth is proposed where the analyte is converted to its hydride form, BiH3, followed by head space preconcentration on a single aqueous drop; final detection was done using electrothermal atomic absorption spectrometry (ETAAS). The preconcentration step was named as headspace single-drop microextraction (HS-SDME). Experimental parameters for hydride generation using both continuous flow and batch technique, ETAAS and finally HS-SDME were optimized. For HS-SDME, Pd, Ni, ...
