THE EFFECT OF a-SiN:H AND a-Si:H SURFACE ROUGHNESS OF TFT BY PE/RACVD

International Journal of Modern Physics B, 2010
This paper describes the influence of surface roughness on the mobility of a - SiN : H and a - Si : H . For the a - SiN : H deposited by PECVD, the roughness was 0.832 nm. The a - SiN : H layer composed of (PECVD 150 nm + RACVD 100 nm) had better characteristic of roughness than the a - SiN : H layer (PECVD 250 nm) by 47%. The roughness of the a - Si :

DEPOSITION OF M—C (M = Cr, Mn, Fe) FILMS BY MAGNETRON SPUTTERING

Modern Physics Letters B, 2005
Thin films of M — C ( M = Cr , Mn , Fe ) have been deposited on silicon substrates by magnetron sputtering. It was found that interdiffusion between carbide films and silicon substrates occurred for Mn — C/Si and Fe — C/Si samples. The hardness and elastic modulus of the Cr — C films were around 16 ± 1 GPa and 210 ± 21 GPa , respectively.

DESIGN & OPTIMIZATION OF AN I-RTD HYBRID THz OSCILLATOR BASED UPON In_1−xGa_xAs/GaSb_yAs_1−y HETEROSTRUCTURE SYSTEMS

International Journal of High Speed Electronics and Systems, 2007
An In 1− x Ga x As / GaSb y As 1− y hetero-system with staggered band-lineups as solid-state platform for design of an interband resonant double-barrier tunneling diode (I-RTD) based optically-pulsed (OT) hybrid device for generating THz oscillations is theoretically investigated.

Metamemory and Memory for a Wide Range of Font Sizes: What is the Contribution of Perceptual Fluency?

Journal of Experimental Psychology. Learning, Memory and Cognition, 2019
Words printed in a larger 48-point font are judged to be more memorable than words printed in a smaller 18-point font, although font size does not affect actual memory. To clarify the basis of this font size effect on metamemory and memory, 4 experiments

PROPERTIES OF Y_1-XSR_XBA_2-XLA_XCU₃O_Y CARRIER COMPENSATION SYSTEM

International Journal of Modern Physics B, 2007
The samples of Y 1-x Sr x Ba 2-x La x Cu 3 O y (YSBLCO) were synthesized and characterized by DC magnetization measurements and X-ray diffraction. The structures of the samples were refined by Rietveld method. Although the carrier concentration in the samples is constant at different dopant levels, the superconductivity evidently changes. We

REACTIVE RESONANCE AND FORMATION MECHANISM STUDIES OF THE H + NO → N + OH OR O + NH REACTION

Journal of Theoretical and Computational Chemistry, 2006
The partial potential energy surface (PPES) of H + NO → N + OH or O + NH of 3A″ symmetry is first constructed using QCISD (T) method with 6-311++g** basis set, and then we speculate the existence of the scattering resonance states of these reactions.

INDUCED DEFECTS IN a-Si:H/a-SiNx:H MULTILAYERS BY USE OF A POSITRON ANNIHILATION TECHNIQUE

Modern Physics Letters B, 1996
In a - Si : H / a - SiN x: H multilayers, in addition to induced distortions, there are a large number of induced defects in the interface regions between a-Si:H and a - SiN x: H due to structural mismatch. In this experiment, we measured a series of a - Si : H / a - SiN x: H (x= 0.5) multilayers by the positron annihilation technique (PAT) and, on ...

HIGH-FIELD TRANSPORT PROPERTIES OF T'-Ln_2-xCe_xCuO₄ (Ln=Nd, Pr, La)

International Journal of Modern Physics B, 2002
We report low-temperature magnetotransport in the normal state of the electron-doped superconductors, Nd 2-x Ce x CuO 4, Pr 2-x Ce x CuO 4, and La 2-x Ce x CuO 4, by suppressing the superconductivity with high magnetic fields. The normal state ρ-T curve shows an up-turn at low temperatures, which has a log T dependence with saturation at lowest ...
