چکیده

Article history: Received 22 December 2016 Received in revised form 12 June 2017 Accepted 15 June 2017 Available online xxxx PdGe contact fabrication on Se-doped Ge(001) is investigated. PdGe thin film resistivity is two times lower if the PdGe layer is grown by Pd reactive diffusion on Se-doped Ge, compared to PdGe layer grown in the same condition on Se-freeGe. The phase sequence and thephase growth kinetics during Pd reactive diffusionwithGe are not modified by the presence of Se atoms. However, the PdGe film texture is different with Se, and Se segregates at the PdGe/Ge interface. These results suggest that Se atoms may be used to produce efficient contacts on n-type Ge. © 2017 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

Fabrication and Investigation of Se-Ge Glass-Ceramics in the Presence of Ga and Sn Additives

The Chalcogenide glasses were fabricated by melting and quenching techniques in the Se-Ge system at the presence of 1mol% Ga and 3, 5, and 7mol% Sn. Differential Scanning Calorimetry (DSC) analysis was conducted to extract the heat treatment of the samples. Fourier Transform Infrared (FTIR) spectroscopy analysis was also performed in a range of 2-16µm. The Glass samples were heat-treated at 450...

Fabrication and Structural Characterization of Se-Ge Chalcogenide Glasses by Means of Melt Quenching Technique

The structural and optical characterization of Se-Ge alloys during melt quenching technique was the goal of this study. In this regards, five different samples of Se100-xGex (x= 10, 20, 30, 40, 50) were prepared by conventional melt quenching in quartz ampoule. The produced samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calori...

A high-responsivity photodetector absent metal-germanium direct contact.

We report a Ge-on-Si photodetector without doped Ge or Ge-metal contacts. Despite the simplified fabrication process, the device shows a responsivity of 1.14 A/W at -4 V reverse bias and 1.44 A/W at -12V, at 1550 nm wavelength. Dark current is less than 1µA under both bias conditions. We also demonstrate open eye diagrams at 40Gb/s.

The computational study of adsorption of carbon monoxide on pristine and Ge-doped (6,0) zigzag models of BNNTs

The aim of this research is studying the effects of Ge-doped on CO adsorption on the outer and inner surfaces of (6, 0) zigzag model of boron nitride nanotube (BNNTs) by using DFT theory. For this purpose, eight models of CO adsorption on the surfaces of BNNTs are considered. At first step, all structures were optimized at B3LYP and 6-31G (d) standard base set and then the electronic structure,...

Fabrication of corrugated Ge-doped silica fibers.

We present a method of fabricating Ge-doped SiO2 fibers with corrugations around their full circumference for a desired length in the longitudinal direction. The procedure comprises three steps: hydrogenation of Ge-doped SiO2 fibers to increase photosensitivity, recording of Bragg gratings with ultraviolet light to achieve modulation of refractive index, and chemical etching. Finite-length, rad...
