We report a scanning probe technique that can be used to measure charging of localized states on conducting or partially insulating substrates at room temperature under ambient conditions. Electrostatic interactions in the presence of a charged particle between the tip and the sample is monitored by the second order flexural mode, while the fundamental mode is used for stabilizing the tip-sample separation. Cycling the bias voltage between two limits, it is possible to observe hysteresis of the second order mode amplitude due to charging. Results are presented on silicon nitride films containing silicon nanocrystals. (c) 2008 American Institute of Physics.

Thin-film transistors based on poly, (3,3 '''-dialkyl-quarterthiophene) and zinc oxide nanowires with improved ambient stability
Vieira, Sara M. C.; Hsieh, Gen-Wen; Ünalan, Hüsnü Emrah; Dag, Sefa; Amaratunga, Gehan A. J.; Milne, William I. (AIP Publishing, 2011-03-07)
The ambient stability of thin-film transistors (TFTs) based on zinc oxide (ZnO) nanowires embedded in poly (3,3'''-dialkyl-quarterthiophene) was monitored through time dependence of electrical characteristics over a period of 16 months. The hybrid-based TFT showed an initial hole mobility in the linear regime of 4.2 x 10(-4) cm(2)/V s. After 16 months storage in ambient conditions (exposed to air, moisture, and light) the mobility decreased to 2.3 x 10(-5) cm(2)/V s. Comparatively the organic-based TFT lost...
Terahertz imaging using an interferometric array
Federici, JF; Gary, D; Schulkin, B; Huang, F; Altan, Hakan; Barat, R; Zimdars, D (AIP Publishing, 2003-09-22)
Most methods of imaging in the terahertz (THz) spectral region utilize either pulsed-laser sources or require the THz generation and detection sources to be phase coherent. The application of interferometric imaging to the THz range is described. Interferometric imaging offers considerable advantages in this regard due to its ability to image with only a handful of detector elements, image many sources of THz radiation at once, image incoherent as well as coherent sources, and provide spectral information a...
Electric dipole moments of charged leptons and lepton flavor violating interactions in the general two Higgs doublet model
Iltan, EO (American Physical Society (APS), 2001-07-01)
We calculate the electric dipole moment of the electron using the experimental result of the muon electric dipole moment and upper limit of the BR(mu-->e gamma) in the framework of the general two Higgs doubler model. Our prediction is 10(-32) e cm, which lies in the experimental current limits. Further, we obtain constraints for the Yukawa couplings )over bar>(D)(N,taue) and )over bar>(D)(N,tau mu). Finally, we present an expression which connects the BR(tau-->mu gamma) and the electric dipole moment of th...
Spectroscopic study and numerical simulation of low-pressure radio-frequency capacitive discharge with argon downstream
Tanisli, Murat; Rafatov, İsmail; Sahin, Neslihan; Mertadam, Sercan; Demir, Suleyman (Canadian Science Publishing, 2017-02-01)
In this study, the characteristic properties and plasma parameters of capacitive radio frequency (RF) argon (Ar) discharge and supplementary discharge at low pressure are investigated with optical emission spectroscopy (OES). The wavelengths of spectral lines from OES are obtained between 650-900 nm. Using OES lines and related experimental data, the electron temperatures for different RF power, flow, and measurement periods are determined. Eventually, the properties of plasma including the electron tempera...
Generation of 2-mu J 410-fs pulses from a single-mode chirped-pulse fiber laser operating at 1550 nm
Pavlova, Svitlana; Rezaei, Hossein; Pavlov, Ihor; Kalaycioglu, Hamit; Ilday, Fatih Omer (Springer Science and Business Media LLC, 2018-10-01)
We report on a simple, robust, femtosecond chirped-pulse-amplification system, based on Er-and Er-Yb-doped fibers, operating at a central wavelength of 1555 nm. The entire system is constructed from commercially available fiber components, except the grating compressor, for easy duplication by other researchers. The laser system produces chirped pulses with up to 4 mu J of pulse energy at 250 kHz. After dechirping, the pulse duration is 410 fs and the pulse energy is reduced to 2 mu J. The repetition rate o...
