An Analytical Solution to a Double-Gate MOSFET with Doped Body

Agarwal N., Bandhawakar G., Amity School of Engineering & Technology, Amity University, IN

ABSTRACT A CMOS scaling is approaching the limit imposed by gate oxide tunneling. Double gate MOSFET (DGMOSFET) with undoped body has become very attractive for scaling CMOS devices down to nanometer size. Device simulation predict [...]

Solution-processed ZnO Single Nanoparticle Transistor Using Water-based Dispersions

Wolff K., Hilleringmann U., University of Paderborn, DE

The integration of printable transistors is an issue of recent work. Different proposals base on ZnO nanoparticle inks, which have to undergo a post-deposition annealing in order to improve the film quality and burn away [...]

Anodized titanium oxide containing highly ordered, vertically oriented TiO2 nanotube arrays is a nanomaterial architecture that shows promise for diverse applications. In this paper, an anodization synthesis using HF-free aqueous solutions is described. The anodized [...]

Flexible Morphology Control of Nanotube Arrays from Glancing Angle Deposition

Huang Z.F., Harris K.D., Brett M.J., University of Alberta, CA

Recently, silicon nanotubes (SiNTs) have attracted considerable attention. However, it has been challenging to grow SiNTs without any template. Another challenge is to engineer the shape of SiNTs, which to date has been limited mostly [...]

Pulsed laser co-deposition of titania with Fe: chemistry, local atomic structure, and light-dependent magnetic properties

Negrila C., Logofatu C., Socol G., Macovei D., Teodorescu C.-M., National Institute of Materials Physics, RO

Transition metal doped titania has been revealed as a promising diluted magnetic semiconductor. We report the synthesis of TiO2:Fe and of mixed Ti and Fe oxides by pulsed laser deposition. The obtained layers were analyzed [...]

Fabrications of Bifunctional Janus and Triblock Saturn Colloids

Lin C.C., Ho C.-C., Chang C-C, Kuo C., National Cheng Kung University, TW

A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer [...]
