This paper proposes a quantum switching on crossed cube, the diameter of the crossed cube is almost half of that of the hypercube, to execute quantum walks. Quantum walks can be implemented in the hypercube and general graphs. Hypercube is a regular graph. According to quantum walk algorithm, the system can preserve unitary property of quantum walks. In the regular graph, to develop quantum walks...
This paper presents a novel technique for long survival observation of Caenorhabditis elegans (C. elegans) inside Environmental-SEM (E-SEM) for nanomanipulations. We have developed the nanorobotic manipulation system inside an Environmental-Scanning Electron Microscope (E-SEM) integrated optical microscope (OM) for nanobiomanipulation platform. Our platform provides a real-time high resolution image...
The technique to construct the artificial organ made of cultured cells is required in many fields such as tissue engineering and drug development. However, the tissue-like construction more than 200 µm thick has central hypoxia and results in necrosis because of the limitation of diffusion of materials. Then, we will propose a method to form a tissue-like construction including vascular network in...
Production of modern microelectronic devices needs advanced materials and packaging technologies oriented towards the miniaturization and high reliability of the systems. Nano sized silver can be treated as such advanced material and it is used in modern packaging technologies, especially for flexible electronics. The paper presents information about the practical use of silver particles with the...
In this work, the planar HKMG MOS devices are fabricated on (100) wafer with p-substrate. To improve the samples' interface roughness between the Si/Ge film and the interface layer, three different clean treatments are considered to fabricate the MOS devices. Among processes, the experiment indicates that HF and water rinse can present hydrogen termination to bond silicon as a good passivation. The...
Nano-diamond slurry was got by mixing with Nano-diamond powder, ethyl cellulose and solvent in a certain quality. Then the mixed solvent was dropped on ultra-white glass which fixed on sol-gel glue rejection machine. The machine was set to 3000 r/ min. After sintering, Nano-diamond film was got. Sintered glass was treated as the window layer of solar battery, and then conversion efficiency and impact...
In this paper we investigate the use of phase-change memory (PCM) devices as binary probabilistic synapses in a neuromorphic computing system for complex visual pattern extraction. Different PCM programming schemes for architectures with- or without-selector devices are provided. The functionality of the system is tested through large-scale neural network simulations. The system-level simulations...
Multiple-control Toffoli gates are basic building blocks for reversible and quantum circuits. 3-bit Peres gate can be considered as a pair of 3-bit and 2-bit Toffoli gates, which can be implemented with fewer elementary quantum gates (what defines a metric called quantum cost) than the total number of elementary quantum gates required by each of Toffoli gates implemented separately. Due to this property,...
A nano-scale dual-step was made by Focused Ion Beam (FIB). The shape of the nano two-step was measured using Atom Force Microscope (AFM). The parameter values in different location of the nano dual-step are compared, including the height h, the base surface roughness Rabase, the first-step surface roughness Rastep1, the second-step surface roughness Rastep2 and the sidewall inclination θ1, θ2. It...
We propose a method to solve differential problems, and in particular quantum wave equations, with periodic boundary conditions, in the direct space using periodic repetitions of the cardinal sine functions as basis functions, and we adopt it for the solution of the Schrödinger equation and, in graphene nanoribbons, of the Dirac equation. We show that this method, unlike finite-difference approaches,...
In this paper, we have fabricated two-dimensional (2-D) photonic crystals (PhCs) in order to obtain the high light extraction efficiency of InGaN-based Light Emitting Diodes (LEDs) and then we used front-side illuminated micro-photoluminescence (μ-PL) spectroscopy to measure the PL intensity of our InGaN-based LEDs, we also used back-side illuminated inverted microscopy to double check our PL intensity...

This paper reports a new scalable behavioral modeling technique for novel nano crossbar ESD protection structures using Verilog-A language. Accurate models for nano crossbar ESD protection structures with different sizes were developed, which were validated by circuit level simulation and transmission line pulsing ESD measurement.
Carbon-based nanostructures have been the center of intense research and development for more than two decades now. Of these materials, graphene, a two-dimensional (2D) layered material system, has had a significant impact on science and technology in recent years after it was experimentally isolated in single layers in 2004. The recent emergence of other classes of two-dimensional (2D) layered systems...
Considerable attention has been paid to aligned polymer nanofibers because of their appealing mechanical and piezoelectric properties. With modified electrospinning, the aligned poly (vinylidene fluoride) (PVDF) nanofibers can be produced. However, the roles of mechanical stretching and electrical poling during this process require further investigation. Here, we utilize a rotary drum to collect the...
