Post-deposition processes for nanostructures formed by electron beam induced deposition with Pt(PF3)4 precursor
Electron beam induced deposition was performed using a Pt(PF3)4 precursor gas. Self-standing nanowires were produced on the edge of a molybdenum film, followed by two post-deposition processes; electron beam irra...

Electron Beam Nanofabrication and Characterization of Iron Compounds
The production of nanometer-sized oxide structures is of significant interest due to the potential application to nanoelectronics, nanomagnetics and optoelectronics. It is important to place nano-dots or nano-...

3-D TEM observation of xenon nano-precipitates in aluminium crystals
It is known that the inert gas, such as xenon (Xe), is not soluble in typical metals and tends to precipitate in the metals. The Xe-precipitates in Al have been observed with TEM in usual modes, such as the br...

A study of the chain-folded lamellae structure and its array in the isotactic polypropylene spherulites by HAADF-STEM and HV-TEM Tomography techniques
It seems that the knowledge of the morphologies of chain-folded lamellae structure in the bulk crystalline polymers is limited, however, in industry, is out of necessary to understand increasing mechanical pro...

Fabrication of self-standing nanowires, nanodendrites, and nanofractal-like trees on insulator substrates with an electron-beam-induced deposition
Self-standing tungsten nanowires, nanodendrites, and nanofractal-like trees were fabricated on insulator (Al2O3) substrates with a process of electron-beam-induced decomposition in a transmission electron microsc...

Three-dimensional nanofabrication by electron-beam-induced deposition using 200-keV electrons in scanning transmission electron microscope
Attempts were made to fabricate three-dimensional nanostructures on and out of a substrate by electron-beam-induced deposition in a 200-kV scanning transmission electron microscope. Structures with parallel wi...

Selective tungsten deposition into ordered nanohole arrays of anodic porous alumina by electron-beam-induced deposition
The selective deposition of a metal (tungsten) into ordered nanohole arrays of an anodic porous alumina membrane was performed using an electron-beam-induced deposition process. After deposition, the membrane ...

Electron beam-induced deposition using iron carbonyl and the effects of heat treatment on nanostructure
Electron beam induced deposition was performed in a scanning electron microscope with a field emission gun using a precursor of iron carbonyl. Nanometer-sized dots and freestanding rods were produced on a carb...

The size dependence of the nano-dots formed by electron-beam-induced deposition on the partial pressure of the precursor
We have successfully fabricated nano-dots containing W from a metal–organic gas source by electron-beam-induced deposition in an ultra-high vacuum transmission electron microscope. The size of the dots can be ...

Spontaneous alloying of tin atoms into nanometer-sized gold clusters and phase stability in the resultant alloy clusters
Alloying behavior and phase stability has been studied in situ by transmission electron microscopy using clusters in the Au-Sn system. When tin atoms are vapor-deposited onto nm-sized gold clusters, rapid dissolu...

Mass in the Gross-Neveu model.—II
It is shown that results on mass generation in the Gross-Neveu model, that were apparently in conflict, lead to the same physics, being therefore equivalent. This is done by using renormalization group techniq...

Mass in the Gross-Neveu model
A reinterpretation of the Nambu-Jona-Lasinio self-consistent technique allows, in the Gross-Neveu model, for interpreting some recent works on the spontaneous mass generation in a unified way and also for the ...

On renormalization-invariant masses
It is shown that spontaneous generation of the renormalization-invariant mass is possible in infra-red-stable theories with more than one coupling constant. If relations among the coupling constants are permit...
