RF Properties of Carbon Nanotube / Copper Composite Through Silicon Via Based CPW Structure for 3D Integrated Circuits
The development of integrated circuits (ICs) has seen exponential growth in performance over the last couple of decades and has pushed the boundaries for how we use our electronics in our daily lives. The scaling of ICs, and therefore also the performance development, is now starting to slow down when the physical des…
Nanoscale Electrical Characterization of Organized GaAsP Nanowires for Photovoltaic Energy Harvesting
We report the characterization of GaAsP nanowires in view of their photovoltaic applications. The nanowires containing a p-i-n junction were elaborated by molecular beam epitaxy using Be and Si as p- and n- doping impurities. Electron beam induced current microscopy was used to analyze the electrical activity of singl…
Engineered Reliability via Intrinsic Thermomechanical Stability of an Electrodeposited Au-Pt Nanocrystalline Alloy
This research objective of this EELDRD study was to learn to electrodeposit Pt Au alloys with independently controlled composition and grain size. What was accomplished was the capability to electrodeposit PtAu alloys with controlled composition and a nanocrysolline grain size. Nanocrystalline metals as a class and, s…

Determination of Appropriate Overhead Line Insulator in Sumatra due to Contamination Severity
Insulator is one of the important equipment to support electrical power delivery which flow through the transmission line. Considering its very important role, the selection of insulators must be certainly based on deep analysis so that the insulator we choose works properly. There are several standards that can be us…
Modelling of Scatter in the System Matrix for 3D PET Image Reconstruction: a Comparative Study
Compton scattering in positron emission tomography (PET) is a major image degrading effect. In this work, an analytical model for Compton scatter is included in the system matrix of two iterative image reconstruction techniques, maximum likelihood expectation maximization (MLEM) and origin ensemble (OE); their perform…
Fast Chemical Exchange Saturation Transfer (CEST) MRI With Dual-channel Segmented RF Irradiation
The aim of this study was to develop a technique for rapid acquisition of chemical saturation exchange transfer (CEST) images with dual-channel segmented RF irradiation to reduce scan time and enhance contrast. Conventional CEST MRI is implemented with a long radiofrequency (RF) irradiation module, followed by fast im…
Heat Transfer in Nanostructured Si and Heat Flux Control Technique
Heat transfer in Si nanostructure is not only an interesting topic in fundamental physics, but also an important practical study for efficient heat dissipation in electronic devices. In this paper, we discuss characteristic thermal phonon transport property in nanostructured Si membranes, where the dimension is smalle…
Black Silicon Photodiodes for VUV Detection
Black silicon (b-Si) is an emerging material made by modifying silicon with nanostructures for improved photon detection. Photodetectors with b-Si has significantly increased the sensitivity from NIR to the visible wavelengths. Here, we measured the spectral responsivity of b-Si light-trapping photodiodes under Vacuum…
A Simple Evaluation of the Benefit of Combined Kinetic Analysis of Multiple Injection Dynamic PET Scans
The multiple injection dynamic Positron Emission Tomography (PET) scanning is used in the clinical management of certain groups of cancer patients and in medical research. The analysis of such studies can be approached in one of two ways: analyze individual injections separately to recover tracer kinetic information,…
Using CdZnTe Detector with Anti-Collimator Shield to Measure Specific Activity of the Contaminated Soils
From 2011 in the NRC "Kurchatov Institute" carry out the dismantling of the MR multiloop research reactor. Now the reactor and mostly technological equipment in the premises of the reactor were dismantled. Now the measurements of radioactive contamination of the soil under the floor of premises are made. To measure th…
Experimental Study of the Combustion Characteristic of Commercial Bus Floor Leather with Adding Combustion Improver
The combustion characteristic of commercial bus floor leather with adding the different volume of combustion improver (gasoline) was experimentally investigated in the cone calorimeter. The gasoline ranged from 2mL to 10mL. The influence of the irradiance heat flux on the floor leather combustion characteristics had a…
Hydrolysis-Tolerant Hybrid Bonding in Ambient Atmosphere for 3D Integration
In this study, a heterogeneous bonding between organic and inorganic materials was realized at low temperature without vacuum atmosphere, by means of the vapor-assisted vacuum ultraviolet (VUV) surface modification method. In this method, an ultrathin bridge layer was created between the surfaces via the VUV irradiati…
Radiation Hardness Study on a Fully Depleted Pinned Photodiode CMOS Image Sensor
The radiation hardness of a fully depleted Pinned Photodiode (PPD) CMOS image sensor (CIS) has been evaluated with gamma and proton irradiations. The sensors employ an additional n-type implant in pixel which allows full depletion to be achieved by reversing biasing the substrate, and have been irradiated alongside re…
Growth Optimization of Multi-Layer Graphene for Thermal-TSV Application in 3D-LSI
A feasibility study for the continuous formation of multi-layer graphene (MLG) on both through-Si-via (TSV) top surface and all through the TSV sidewall and the bottom surface of high-aspect-ratio TSV by thermal chemical vapor deposition (CVD) technique has been carried out. Both microstructural and μ-Raman studies on…
SEM Characterization of a Silicon Drift Detector for Electron Spectroscopy
Silicon Drift Detectors, widely employed in X-ray spectroscopy for high-resolution and high-count-rate applications, have found their application also in the β-decay spectroscopy measurements. The detection of electrons, in place of photons, yields to a different response of the detector. Electrons are absorbed in the…
